Question

A sphere has a surface area of 2,122.64 square meters. Which equation can you use to find the radius?

2,122.64 = 4pie r
2,122.64 = 4pier²
2,122.64 = 4(pier)2
2,122.64 = (4pier)2

Answer 1

12.997

Step-by-step explanation:

this is the answer but i don't understand the rest of this question :

. Which equation can you use to find the radius?

2,122.64 = 4pie r

2,122.64 = 4pier²

2,122.64 = 4(pier)2

2,122.64 = (4pier)2

hope this helps

Answer 2

Step-by-step explanation:
The surface are of a sphere has the formula
SA=4πr2SA=2122.64
so
2122.64= 4πr^2
The answer is the second one
