## What is 75% of the area of a circle with a circumference of 10 units? Round the solution to the nearest square unit.

Answer: 75% of the area of the circle is 6 square units. Step-by-step explanation: Given: Circumference of a circle = 10 units Now we have to find the radius of the circle, then we have to find the area of the circle. Circumference of a circle = 2*π*r     …

## 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

## What’s the approximate area of a segment of a circle with a height 6 m and the length of the chord is 20 m? Round your answer to the nearest whole number. A. 746.67 m2

Hello! The Correct Answer to this would be 100%: Option “85.4”. (Work Below) Given:height = 6mchord = 20 m We need to find the radius of the circle. 20 m = 2 √ [ 6m( 2 x radius – 6 m ) ] 20 m / 2 = 2 √[ 6m( 2 x …

## Please help meee!!!! A circle has its center at (1, 4) and a radius of 2 units. What is the equation of the circle? (x − 1)2 + (y − 4)2 = 4 (x + 2)2 + (y + 4)2 = 2 (x + 1)2 + (y − 4)2 = 4 (x − 1)2 + (y − 4)2 = 2

Answer: A. Step-by-step explanation: We have been given that a circle has its center at (1, 4) and a radius of 2 units. We are asked to write the equation of the given circle. Since we know that the center-radius form of circle equation is: , where (h,k) is the …

## 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 …
