A circle has an area of 12. If the radius is increased by a factor of 2, what is the new area of the circle?

Answered by answersmine AT 22/10/2019 – 02:38 AM A=12. A=π×r^2(area of a circle)π×r^2=12r×2:π×(r×2)^2= π×r^2×4. Here you can see that the calculation is exactly the same as above except from the Factor 4. This Shows that the area is four times bigger than before: 12×4

The following graph shows the demand curve for a group of consumers in the U.S. market (blue line) for Blu-ray players. The market price of a Blu-ray player is shown by the black horizontal line at $150. Each rectangle you can place on the following graph corresponds to a particular buyer in this market: orange (square symbols) for Antonio, green (triangle symbols) for Caroline, purple (diamond symbols) for Dmitri, tan (dash symbols) for Frances, and blue (circle symbols) for Jake. Use the rectangles to shade the areas representing consumer surplus for each person who is willing and able to purchase a Blu-ray player at a market price of $150. (Note: If a person will not purchase a Blu-ray player at the market price, indicate this by leaving his or her rectangle in its original position on the palette.

On December 15, 1791, the Bill of Rights (the first ten amendments to the United States Constitution) were ratified by the states. The Bill of Rights were added to the Constitution to address fears raised by the Anti-Federalists during the ratification of the Constitution that the Constitution did not provide …

A semi- circle sits on top of a rectangle. Find it’s area and perimeter. Use 3.14 for pi. The height is 4in and the base is 3in

Check the picture below if the width or base of the rectangle is 3 units, that means the diameter of the semi-circle is 3, and thus the radius is half that, notice the red radius line the area of the figure is the area of the rectangle 3×4, plus the …

Brenda throws a dart at this square-shaped target: Part A: Is the probability of hitting the black circle inside the target closer to 0 or 1? Explain your answer. (5 points) Part B: Is the probability of hitting the white portion of the target closer to 0 or 1? Explain your answer. (5 points)

Either way.  The probability of hitting the circle is: P(C)=Area of circle divided by area of square P(W)=(area of square minus area of circle divided by area of square P(C)=(πr^2)/s^2 P(W)=(s^2-πr^2)/s^2 … Okay with know dimensions, r=1 (because r=d/2 and d=2 so r=1), s=11 we have: P(inside circle)=π/121  (≈0.0259  or …

PLEASE HELP Mr. Utterson the lawyer was a man of a rugged countenance, that was never lighted by a smile; cold, scanty and embarrassed in discourse; backward in sentiment; lean, long, dusty, dreary, and yet somehow lovable. At friendly meetings, and when the wine was to his taste, something eminently human beaconed from his eye; something indeed which never found its way into his talk, but which spoke not only in these silent symbols of the after-dinner face, but more often and loudly in the acts of his life. He was austere with himself; drank gin when he was alone, to mortify a taste for vintages; and though he enjoyed the theatre, had not crossed the doors of one for twenty years. But he had an approved tolerance for others; sometimes wondering, almost with envy, at the high pressure of spirits involved in their misdeeds; and in any extremity inclined to help rather than to reprove. "I incline to, Cain's heresy*," he used to say. "I let my brother go to the devil in his quaintly 'own way.'" In this character, it was frequently his fortune to be the last reputable acquaintance and the last good influence in the lives of down-going men. And to such as these, so long as they came about his chambers, he never marked a shade of change in his demeanour. No doubt the feat was easy to Mr. Utterson; for he was undemonstrative at the best, and even his friendship seemed to be founded in a similar catholicity of good-nature. It is the mark of a modest man to accept his friendly circle ready-made from the hands of opportunity; and that was the lawyer's way. His friends were those of his own blood or those whom he had known the longest; his affections, like ivy, were the growth of time, they implied no aptness in the object. Hence, no doubt, the bond that united him to Mr. Richard Enfield, his distant kinsman, the well-known man about town. It was a nut to crack for many, what these two could see in each other, or what subject they could find in common. It was reported by those who encountered them in their Sunday walks, that they said nothing, looked singularly dull, and would hail with obvious relief the appearance of a friend. For all that, the two men put the greatest store by these excursions, counted them the chief jewel of each week, and not only set aside occasions of pleasure, but even resisted the calls of business, that they might enjoy them uninterrupted. *The biblical story of Cain and Abel is a story about two brothers who gave offerings to God. Abel’s offering was accepted by God, but Cain’s was not. Jealous, Cain killed his brother. When God asked Cain where Abel was, Cain said, “Am I my brother’s keeper?” By saying this, Cain implied that what his brother did was his own business. (Genesis 4:1-16) What is significant about “Cain’s heresy” in this passage? A.It shows that Mr. Utterson is a deeply religious and righteous person. B.It shows that Mr. Utterson tries not to judge others or get in their business. C.It shows the Mr. Utterson wants to steal from other people’s businesses. D.It shows that Mr. Utterson does not believe in any kind of religion at all.
