Answer: 7

Step-by-step explanation:

A barrel has a shape of a cylinder, therefore volume of a barrel is Area x height = pi× r^2 h

Where pi = 3.14; r = radius and h = height

Given that height = 4 ft

Diameter = 1.5 ft

Step 1: divide diameter by 2 to get the length of the radius = 1.5 /2 = 0.75

r = 0.75; r^2 = 0.75 x 0.75 = 0.5625

Step 2: slot the values into the formula

3.142 × 0.5625 x 4

= 7cubic cm
