Question

The surface area of a sphere is 314 square meters. Which equation can be used to find the radius of the sphere?

Recall the formula S A = 4 pi r squared.
314 = 4 pi r
314 = 4 pi r squared
314 = (4 pi r) squared
314 = 4 pi r squared + 2 pi r

Answer 1

314 =4 Pi (r squrared)

Explanation:

so second option is the right answer
