What is the volume of a sphere with a surface area of ​ 16π ​ft²?

What is the volume of a sphere with a surface area of ​ 16π ​ft²? a. 8π ​ ft³ b. 1023π ​​ ft³ c. 2113π ​ ft³ d. 8513π ft³

Sphere Surface Area     =     4 • π • r²
For it to equal 16 PI, then radius must equal 2
4*PI*2*2 = 16 PI

Sphere Volume   =   4/3 • π • r³

Sphere Volume   =   4/3 • π • 2^3

Sphere Volume   =  4/3 *PI * 8

Sphere Volume   =  32 / 3 PI

Sphere Volume   =  10.666 PI cubic feet AND I think that is answer B
which SHOULD read 10 (2/3) PI ft^3

the answer is 10 2/3. hope this helps

the answer is 10 2/3. hope this helps

1=1.19m, 2=232.35ft2, 3=916.09cm2, 4=3.375km, 5=3.54ft, 6=67.02mm3, 7=13ft
i hope you find these answers useful
