Question

5. Find the volume of a cylinder with radius 3 cm and height 5 cm?​

Answer 1

Step-by-step explanation:

r=3

h=5

V≈141.37cm³

(V=πr2h=π·32·5≈141.37167cm³)

Answer 2

$\huge\underline{\overline{\mid\star{\sf{\pink{Answer}}\star\mid}}}$

${ \bold { \underline{\large{Given: }}}} \:$

Radius = 3cm

Height = 5cm

${ \bold { \underline{\large{To \: Find : }}}} \:$

Volume of the cylinder

${ \bold{ \underline{\large{Solution : }}}} \:$

$\large\boxed{\pink{\tt{ Volume\:of \:cylinder \:=\:2πrh :-}}}$

So,

V = 2πrh

V = 2 × $\frac{22}{7}$ × 3 × 5

V = 2 × $\frac{22}{7}$ × 15

V = 30 × $\frac{22}{7}$

V = $\frac{66}{7}$

$\large\boxed{\purple{\tt{V\:=\:9.4285714286}}}$

What is cylinder?

In mathematics, a cylinder is a three-dimensional solid that holds two parallel bases joined by a curved surface, at a fixed distance.

How many sides does a cylinder have?

3 sides

A cylinder has 1 side which wraps around circular areas in the two ends. If the ends are enclosed then there are 2 circular sides for a total of 3 sides, two of which are flat circles and one curved side.
