Question

Find the circumference and area of a circle A with a diameter of 26 inches.

Answer 1

Answer:

Circumference: 81.681 in; Area: 530.929 in

Step-by-step explanation:

To find circumference we use the formula pi x diameter. Which in this case is pi x 26 in, or approximately 81.681 in.

For the area, we use pi x r^2. r = 1/2 d, so r = 13in. Therefore, the area is equal to 169 x pi in, which is about 530.929 in.
