Question

what is the surface area of a sphere with radius 2?

A. 4π units2
B. 16π units2
C. 2π units2
D. 8π units2

Answer 1

A.

Answer 2

r u sure?

Answer 3

SA = 4. pi. r^2
SA = 4. pi. 2^2
SA = 4.pi.4
SA = 16 pi

Answer 4

@thihaaung Ill tell you how I got that

Answer 5

u gave me wrong answer

Answer 6

Sphere Surface Area = 4 π r2

Answer 7

@ivettef365 yea thats what I thought

Answer 8

sure you did

Answer 9

@ivettef365 I thought it was 4 π r2 but its not sorry
