Volume of the entire ball"= \\frac{4}{3} \\pi ^3"

Volume "=\\frac{4}3*\\frac{22}7*2^3"

Volume "=33.524 in^3"

The volume of the hollow area of the ball "=\\frac{4}3 \\pi^3"

V"=\\frac{4}3*\\frac{22}7*[2-0.05]^3"

"V=31.0719 in^3"

Volume of copper "=33.524-31.072"

"V of \\space copper =2.452in^3"

Density of Cu"=0.324 lb\/in^3"

Mass of Cu"=Density \\space of \\space Cu*Volume \\space of \\space Cu"

Mass of Cu"=0.324*2.452"

Mass of Cu"=0.794 lb"

Weight of copper "=0.794 *2.204*10"

Weight of copper"=17.510kg"
