Answer:

760.25

Step-by-step explanation:

The formula for the surface area of a sphere is A=4πr².

r=the radius, or half of the diameter, of the circle.

when you plug in the radius and answer the formula, you should get 1520.5.

You should then divide it by 2 since we are trying to find half of the circle.
