Question

Find the volume of a cylinder with a diameter of 6 inches and a height that is three times the radius use 3.14 for pie and round your answer to the nearest 10th and you may only enter numerals decimal points

Answer 1

254.34 in^3

Explanation:

Volume of a cylinder is V=pi*r^2*h

Since r=6/2=3, and h=3r=3*3=9, then we solve for V:

V=3.14*3^2*9

V=3.14*9*9

V=3.14*81

V=254.34

So the volume of the cylinder is 254.34 in^3

Answer 2

Answer: volume = 254.3 inches³

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,

Diameter = 6 inches

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

Height = 3 × radius = 3 × 3 = 9 inches

Therefore,

Volume = 3.14 × 3² × 9

Volume = 254.3 inches³ to the nearest tenth
