Question

The circumference of a base of cylinder is 44 cm and height is 15 cm what is the volume of cylinder

Answer 1

Given:

Circumference of the base of cylinder is 44 cm.

Height of the cylinder is 15 cm.

Find:

Volume of cylinder

Solutions:

Let the radius of the cylinder be 'r' cm.

We know that,

The circumference of base of cylinder = 2πr

=> 44 = 2πr

=> 44 = 2 × 22/7 × r

=> 44 = 44/7 × r

=> 44 × 7/44 = r

=> 7 = r

=> r = 7cm

The radius of the cylinder is 7cm.

Now,

Volume of the cylinder = πr²h

=> πr²h

=> 22/7 × (7)² × 15

=> 22/7 × 49 × 15

=> 22 × 7 × 15

=> 2310cm³

Hence, the volume of cylinder is 2310 cm³.

I hope it will help you.

Regards.

Answer 2

Answer:

=> (4x + 6)/(5x + 6) = 6/7

=> 7(4x + 6) = 6(5x + 6)

=> 28x + 42 = 30x + 36

=> 28x - 30x = 36 - 42

=> -2x = -6

=> x = -6/-2

=> x = 3
