What is the approximate surface area of a sphere 15yd?

Hi there!

Unfortunately, I cannot view the image you have linked. Instead, I will walk you through how to solve for the surface area.

First, find the value of your radius. If you're given a diameter, you'll need to divide that in 2. If you're given a circumference, use the circumference formula (pi x diameter, or 2 x pi x radius) to find the radius.

Second, use the formula for the surface area of a sphere, which is SA = 4 x pi x r^2. Plug in the radius, square it, then multiple the radius squared by 4 to find the surface area in terms of pi. If you're looking for to the nearest tenth, or not in terms of pi, multiply the value we just found by pi.

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

Ibelieve it's a. 2.2 - x = -10.85 (plz tell me if it's right : ) )
