Question

What is the volume of a sphere with a radius, r = 0.5?

Use 3.14 for a and be sure you round your answer to two decimals.
TO

Answer 1

V = 0.52 cm³

Explanation:

radius r = 0.5 cm

volume V = 0.523333333 cm³

surface area A = 3.14 cm²

circumference C = 3.14 cm

In Terms of Pi π

volume V = 0.166666667 π cm³

surface area A = 1 π cm2

circumference C = 1 π cm

Agenda: r = radius

V = volume

A = surface area

C = circumference

π = pi = 3.1415926535898

Volume of a sphere:

V = (4/3)πr³

Circumference of a sphere:

C = 2πr

Surface area of a sphere:

A = 4πr²
