Question

A cylinder has a base diameter of 8ft and a height of 20ft. What is its volume in cubic ft, to the nearest tenths place?

Answer 1

Answer:

• Volume= 1004.8 cubic feet

Solution:

Volume of a cylinder is the product of area of circle and it's height i.e:

‎ㅤ‎ㅤ‎ㅤ➙ V = πr²h

Here, we are given that:

• Diameter of base = 8 ft

➝ Radius ( r ) = d / 2

➝ Radius ( r ) = 8 / 2

➝ Radius ( r ) = 4 ft

• Height of cylinder = 20 ft

Therefore, volume:

➝ V = πr²h

➝ V = π ( 4 )² 20

➝ V = 3.14 × 16 × 20

➝ V = 3.14 × 320

➝ V = 1004.8 ft³

Answer 2

Answer:

Volume is 1004.8ft³

Step-by-step explanation:

Given:-

• Base diameter of cylinder :- 8ft , radius :- 4ft.
• Height :- 20ft.

To find :-

• Volume of Cylinder

Solution:-

• Volume of Cylinder :- πr²h

Putting the values ,

Volume = 3.14 × 4² × 20 ft³

Volume:- 1004.8 ft³
