Question

v. A wooden cylinder of length 21cm has a diameter of 14cm. What is the volume of the
cylinder?​

Answer 1

Explanation:

So, volume of cylinder is π × (radius )2 × height

Given

length = height = 21 CM

diameter = 14 CM

radius = d/2 (because radius is half of the diameter)

radius= 7

so, put all the value -

volume of cylinder = π × r2× h

= 22/7×7×7× 21

= 3234

hence, the volume of cylinder is 3234

Answer 2

Answer:

3234 cm³

Step by step explaination:

Here ,

h= 21cm. , d= 14cm.

so, r = d/2 = 14/2 = 7 cm.

As we know ,

Volume of cylinder = π r² h

=( 22/7)× 7² × 21

= 22×7×21

= 3234 cm³
