A right circular cylinder has a height of ​ 19 3/4 ​ ft and a diameter ​ 1 2\5 ​ times its height.
alexira [117]

Answer:

Volume of cylinder is  34833.21 ft³

Step-by-step explanation:

Given : A right circular cylinder having height 19\frac{3}{4} ft and diameter \frac{12}{5} ​times its height.

Given : diameter \frac{12}{5} ​times its height that is

diameter \frac{12}{5} ​times  19\frac{3}{4}  that is

Diameter = \frac{12}{5} \times \frac{79}{4} ​

Diameter = \frac{237}{5} ft

Radius is half of diameter,

Radius = \frac{1}{2} \times \frac{237}{5}=\frac{237}{10} ft

\text{Volume of Cylinder}=\pi r^2h

Substitute the values, we get,

\text{Volume of Cylinder}= \pi (\frac{237}{10})^2 \times \frac{79}{4}

\text{Volume of Cylinder}= \times 3.14 \times (23.7)^2 \times 19.75

\text{Volume of Cylinder}= \times 3.14 \times (23.7)^2 \times 19.75

\text{Volume of Cylinder}=34833.21

Thus, volume of cylinder is  34833.21 ft³
