]]>**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 [π = 3.14]

2*3.14*r = 10

6.28r = 10

Dividing both side by 6.28, we get

r = 10/6.28

r = 1.59

Now let’s find the area of the circle.

The area of the circle = π*r^2

= 3.14*1.59*1.59

The area of the circle = 7.94, which is 100 %

Now we have to find the 75% of the area of the circle.

75% = 0.75

75% of the area of the circle = 0.75*7.94

= 5.95

To round off to the nearest whole number, we get 6 square units.

With a uniform electric field, flux go along parallel paths, then flux is therefore proportional to the cosine of the angle rotated.

0 degree rotation => cos(0)=1 => 100% of flux.

60 degrees rotation => cos(60) => 0.5 => how many % of flux?

]]>The formula for calculating the direct labor standard is:

Direct labor standard = Basic wages + Payroll tax

or

Direct labor standard = Basic wages + 25% of Basic wages

Substituting the given values into the equation:

Direct labor standard = $19 + 0.25 * $19

**Direct labor standard = $23.75**

A=12. A=π×r^2(area of a circle)

π×r^2=12

r×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

Hello!

The Correct Answer to this would be 100%:

Option “85.4”.

(Work Below)

Given:

height = 6m

chord = 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 radius – 6 m ) ] / 2

10 m = √ [ 6m( 2 x radius – 6 m ) ]

(10 m)² = √[ 6m( 2 x radius – 6 m ) ] ²

100 m² = 6 m( 2 x radius – 6 m )

100 m² = 12 m x radius – 36 sq m

100 m² + 36 m² = 12 m x radius – 36 m² + 36 m²

136 m² = 12 m x radius

136 m² / 12 m = 12 m x radius / 12 m

11.333 m = radius

the area beneath an arc:

Area = r² x arc cosine [ ( r – h ) / r ] – ( r – h ) x √( 2 x r x h – h² ).

r² = (11.333 m)² = 128.444 m²

r – h= 11.333 m – 6 m = 5.333 m

r * h = 11.333 m x 6 m = 68 m²

Area = 128.444 m² x arc cosine [ 5.333 m / 11.333 m ] – 5.333 m x √[ 2 x 68 m² – 36 m² ]

Area = 128.444 m² x arc cosine [ 0.4706 ] – 5.333 m x √ [ 100m² ]

Area = 128.444 m² x 1.0808 radians – 5.333 m x 10 m

Area = 138.828 m² – 53.333 m²

Area = 85.4 m²

Hope this Helps! Have A Wonderful Day! 🙂

And as Always…
