Question

A cylinder has a radius of 4.5 inches and a height of 10 inches. What is the volume of the cylinder? Use 3.14 for π and round your answer to the nearest cubic inch if needed.

Answer 1

the correct option would be b

Answer 2

• 636 inches (Rounded)

Explanation:

We know that:

• r = 4.51 inches
• h = 10 inches
• Volume formula = πr²h

Solution:

• π x r² x h = Volume
• => 22/7 x 4.5² x 10 = Volume
• => 22/7 x 4.5 x 4.5 x 10 = Volume
• => 22/7 x 20.25 x 10 = Volume
• => 22/7 x 202.5 = Volume
• => 636 inches (Rounded)

Hence, Option B is correct.
