This half cylinder fish tank has a tank height of 25 inches and a tank diameter of 22 inches. What is the volume of this fish ta

Xelga [282]

Answer:

The volume of this fish tank is $9498.5\ \text{inches}^3$ .

Step-by-step explanation:

Height of cylinder fish tank is 25 inches

Diameter of a tank is 22 inches

It is required to find the volume of this fish tank. The formula for the volume of a fish tank is given by :

$V=\pi r^2 h$

r = radius = 11 inches

h = height = 25 inches

$V=3.14\times (11)^2\times 25\\\\V=9498.5\ \text{inches}^3$

So, the volume of this fish tank is $9498.5\ \text{inches}^3$ .
