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.
