Question

A tank on a road roller is filled with water to make the roller heavy. The tank is a cylinder that has a height of 6 feet and a radius of 2 feet. One cubic foot of water weighs 62.5 pounds. Find the weight of the water in the tank.
To the nearest whole number, the water weighs ____ pounds.

Answer 1

First, we find the volume.

V=pir^{2}h
V=pi(2)^{2}6
V=pi(4)6
V=75.4

Now, we use this as the capacity and multiply it by the weight of the water.

75.4*62.5=4712.5

4712.5, the 5 means we round up, so your answer is 4713. Hope this helped!

Answer 2

Since one cubic foot of water weighs 62.5 pounds, hence the weight of 75.36 ft³ will be 4710 pounds

How to find the volume of a cylinder

The formula for calculating the volume of a cylinder is expressed as:

V = πr²²h

where:

r is the radius

h is the height of the cylinder

Given the following parameters:

r = 2fft

h = 6feet

Calculate the volume

V = 3.14 * 4 * 6

V = 75.36 ft³

Since one cubic foot of water weighs 62.5 pounds, hence the weight of 75.36 ft³ will be 75.36 * 62.5 = 4,710 pounds
