Question

A volume of a sphere is 1,766,250 cubic meters. What is the radius of the sphere use 3.14 to approximate pi

Answer 1

The formula for the volume of a sphere is

V=4/3πr³   where r=radius
plug in the data we know
1,766,250m³=4/3πr³
divide both sides by 4/3
1324687.5=πr³
divide both sides by π (3.14)
421875=r³
find the cubic root of 421875
75=r

Answer: r=75m
