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
I hope this is clear, please mark as brainliest answer.
