Question

The diameter of a cylinder is 5 yd. The height is 4 yd. volume of the​ cylinder? Find the volume of the cylinder.

Answer 1

Using volume formula in terms of cylinder and use units such as yd carefully for conversions

Explanation:

Diameter = 3 yd

Radius (r) = 3/2 = 1.5 yd

height (h) = 4 yd

Volume (V) = πr²h

=π * (1.5)² * 4 =π *2.25 *4

= 9π cubic yd

Answer 2

• Volume of cylinder is 78.5 cubic yd.

Explanation :

Given :-

• Diameter of cylinder = 5 yd
• Height of cylinder = 4 yd

To Find :-

• Volume of cylinder?

Solution :-

Firstly lets calculate radius of cylinder, as we know that;

• Radius = Diameter/2

Putting all values we get;

➸ Radius = 5/2

➸ Radius = 2.5 yd

Now let's calculate its volume, as we know that;

• Volume of cylinder = πr²h

Putting all values we get;

➸ Volume(cylinder) = 3.14 × (2.5)² × 4

We can write it as;

➸ Volume(cylinder) = 3.14 × 4 × 2.5 × 2.5

➸ Volume(cylinder) = 12.56 × 6.25

➸ Volume(cylinder) = 78.5 cubic yd

• Hence, volume of cylinder is 78.5 cubic yd.
