Question

Find the volume of the sphere to the nearest whole number. Use π = 3.14. r = 12.3.

A. 7,795m ^3
B. 62,358m ^3
C. 5,846m ^3
D. 1,919m ^3

Answer 1

`\text{The formula of the volume of a sphere with a radius R:}\\\\V=(4)/(3)\pi R^3\\\\\text{We have:}\\\\r=12.3\\\pi\approx3.14\\\\\text{substitute:}\\\\V=(4)/(3)\cdot3.13\cdot12.3^3\approx7795\ m^3\\\\\text{Answer:}\ A.\ 7,795\ m^3`
