Question

A cylinder has a base diameter of 6in and a height of 2in. What is its volume in cubic in, to the nearest tenths place?

Answer 1

Answer: volume = 56.52 cubic inches

Step-by-step explanation:

The formula for determining the volume of a cylinder is expressed as

Volume = πr²h

Where

r represents the radius of the cylinder.

h represents the height of the cylinder.

π is a constant whose value is 3.14

From the information given,

base diameter = 6 inches

Radius = diameter/2 = 6/2 = 3 inches

Height = 2 inches

Therefore,

Volume = 3.14 × 3² × 2 = 56.52 cubic inches

Answer 2

Answer: 56.56 cubic in

Step-by-step explanation:

Formula for the volume of a cylinder is = πr²h

where π = 3.142

r = radius of the cylinder

h = height of cylinder.

from the question,

r = diameter ÷ 2 = 6 ÷ 2 = 3 in

h = 2 in

using the formula πr²h, we have,

3.142 × 3² × 2 = 56.556 cubic in

to the nearest tenths place, 56.56 cubic in
