1. Volume of sphere =$4/3×π×r^3$ where r=60 in this case So the volume of quarter-sphere = $\frac{ 1 }{ 4 }×\frac{ 4 }{ 3 }×π×r^3 = \frac{ 1 }{ 3 }×\pi×60^3=226195ft^3$ to the nearest whole number

2. Since each holding tank is congruent, both of them have a radius of 30 feet, height of 110 feet Volume of a cylinder = $\pi×r^2×h$ so volume of each half-cylinder = $\frac{ 1 }{ 2 } ×\pi×r^2×h = \frac{ 1 }{ 2 }×\pi×30^2×110=155509ft^3$ Total volume of both cylinders =$2×155509=311018ft^3$
