a. 512π mm2
b. 1,024π mm2
c. 4,096π mm2
d. 2,048π mm2

Answer 1

Sphere Surface Area     =     4 • π • r²
radius = 16mm
Sphere Surface Area     =     4 • π • 16²
Sphere Surface Area     =    4 • π • 256
Sphere Surface Area     =  1,024 • π
Answer is B

Answer 2

B. 1,024π mm2.

I hope helped.

good luck to you
