Question

a cylindrical tank has a diameter of 5 feet and the distance between the circular bases is 6 feet. find the lateral area of the tank.

Answer 1

Lateral area = 94.2 ft²

Explanation:

The formula for lateral area of cylinder is given as;

A_l = 2πrh

Where;

r is radius

h is height

Now, we are told that the distance between the 2 circular bases is 6ft. Thus, the height is 6ft.

Diameter is given as 5ft.

We know that radius = diameter/2

Thus;radius;r = 5/2 = 2.5 ft

So, lateral area = 2πrh = 2π x 2.5 x 6 = 94.2 ft²

Lateral area = 94.2 ft²
