Question

What is the surface area of a sphere with a radius of 12 centimeters? (Use 3.14 for π.)

A) 1,808.64 cm 2
B) 452.16 cm 2
C) 150.72 cm 2
D) 301.44 cm 2

Answer 1

Formula for surface area of a sphere:
A=4
`\pi`
`r^(2)`
A=4(3.14)(144)
A=4(452.16)
A=1808.64

The answer is A.

Answer 2

Surface Area = 4×π×122 = 1809.5573684677 centimeter^2
