Answer 2

$\text{Find the volume of the cone:}\\\\\text{Use the volume equation for cones:}\\\\\frac{1}{3}\pir^2h\\\\\text{Plug in values:}\\\\\frac{1}{3}\pi7^2(9)\\\\\text{Solve:}\\\\\frac{1}{3}\pi7^2(9)\\\\\frac{1}{3}\pi49(9)\\\\\frac{1}{3}\pi441\\\\147(\pi)\\\\\boxed{\text{Volume: 461.81\,}in^3}}$
