Question

PLEASE HELP!! DUE SOON!!!

Find the surface area of the sphere (I can't upload the pic but I'll give the radius).
Radius 7 m
A. 56π m²
B. 784π m²
C. 392π m²
D. 196π m²

Answer 1

D

Explanation:

This is because the formula is 4×pi×r^2

So 4×pi×7^2

(7^2=49) now plug that in: 4×pi×49

Combine like terms: 4×49=196

Plug that into the equation: 196pi
