A right circular cylinder has a height of 20 1/2 ft and a diameter 1 1/5 times its height.

AfilCa [17]

Height=h=20-1/2=20.5ft
Diameter=1-1/5=1.2
Radius=1.2/2=0.6ft

$\\ \sf\longmapsto V=\pi r^2h$

$\\ \sf\longmapsto V=3.14(0.6)^2(20.5)$

$\\ \sf\longmapsto V=3.14(0.36)(20.5)$

$\\ \sf\longmapsto V=23.17ft^3$
