Question

Hey guys! Leave the answer in terms of pi :)

If circle A has a diameter of 13, what would be the area?

If circle B has a diameter of 6, what would be the area?

Answer 1

a) if the diameter is 13 the radius is 6.5

`(6.5 * 6.5) * \pi = 42.25\pi \\ = 132.7323`
b)if the diameter is 6 the radius will be 3

`(3 * 3) * \pi = 9\pi \\ = 28.27433`
hope this helps
