Answer:
(4225/4)pi units^2
Step-by-step 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
