Answer:

(4225/4)pi units^2

Explanation:

So we need to know the area of a circle formula to find the answer to this question

the formula is A = r^2(pi)

So we have the diameter but we need the radius. The radius is half the diameter so r = 65/2

Now we can plug the radius into the area formula

(65/2)^2*pi =

(4225/4)pi units^2
