Question

A sculptor has just finished creating a large wooden sphere for a sculpture he is working on. The sphere has a radius of 4.3 feet and weighs approximately 10,578.59 pounds. What is the approximate density of the wood used to create the sphere? I need help

Answer 1

Density = mass/volume

the mass is 10578.9 pounds

the volume of a sphere is v = 4/3 πr^3

v = (4/3) (π) (4.3)^3
v = 333.04

10578.9 / 333.04 = 31.76

the final density is 31.76!!
