Question

Circle A has an area of 452.16 ft2 with a radius of 12 ft. If circle B has a radius of 17 ft, what is its area? A. 907.46 ft2 B. 706.49 ft2 C. 709.64 ft2 D. 904.76 ft2

Answer 1

Just use the formula for finsing the area of a circe: 

A=pi*r^2

Insert the value or r:

A=3.14*17^2=907,46 ft^2

Hope that helped

Answer 2

Answer:

The area of the circle B is 907.76 ft² .

Option (A) is correct.

Step-by-step explanation:

Formula

$Area\ of\ a\ circle = \pi r^{2}$

Where r is the radius of a circle.

As given

Circle A has an area of 452.16 ft2 with a radius of 12 ft.

If circle B has a radius of 17 ft.

Here r = 17 ft

$\pi = 3.14$

Put in the formula

Area of a circle B = 3.14 × 17 × 17

                            = 907.76 ft²

Therefore the area of the circle B is 907.76 ft² .

Option (A) is correct.
