Question

find the volume of cylinder whose radius =14m and hight =15m​

Answer 1

Given

Radius of cylinder = 14m

Height of cylinder = 15m

To Find

The Volume of cylinder

Formula

Volume of cylinder = πr²h

Now Put the value on formula

V = 22/7 × 14m × 14m × 15m

V = 22 × 2m × 14m × 15m

V= 44m × 210m²

V = 9240m³

Answer

Volume of cylinder is 9240m³

More Information

Volume = πr²h

Surface area = 2πrh + 2πr²

Lateral area = 2πrh

Base area = πr²

Height = V/πr²

Radius = √(V/πh)

Answer 2

Answer:

Given,

Radius =14 m

Height =15 m

______________________

Volume of cylinder =pi.r².h

=22/7 x 1.4 x 1.4 x 15

=92.4 m³

______________________

Currve surface area =2.pi.r.h

=2 x 22/7 x 1.4 x 15

=132 m²

______________________

| Total surface area =2pi.r² +2pi.r.h

=2 x 22/7 x1.4 x 16.4

=144.32 m²
