Question

A tunnel is cylindrical. The tunnel is 400 m long with radius 2.3 m.

What is the capacity of the tunnel? Give the answer is liters. [Hint: 1 m3 = 1000 L]

Answer 1

6647.6 liters

Explanation:

The volume of a cylinder with end area r and length (or height) h is

V = πr²h

If we substitute 2.3 m for r and 400 m for h, we get:

V = π(2.3 m)²(400 m) = 6647.6 m³ or 6647.6 liters
