Solution
1)
Given data
Radius r = 6 yd
Height h = 15 yd
[tex]\begin{gathered} Volume\text{ of a cylinder = }\pi\text{ r}^2h \\ \pi\text{ = 3.14} \\ Volume\text{ of a cylinder = 3.14 }\times\text{ 6}^2\text{ }\times\text{ 15} \\ Volume\text{ of a cylinder = 1695.6 yd}^3 \end{gathered}[/tex]
2)
Height = 15 feet
Diameter = 14 feet
Radius = Diameter/2 = 14/2 = 7 feet
[tex]\begin{gathered} \text{Volume of cylinder = }\pi\text{ r}^2h \\ =\text{ 3.14 }\times\text{ 7}^2\text{ }\times\text{ 15} \\ =\text{ 2307.9 ft}^3 \end{gathered}[/tex]
