Question

find the curvedsurface area of the cylinder it's r = 2.5, h= 7cm​

Answer 1

Answer:

Given:

A cylinder in which:

1. Radius = r = 2.5 cm
2. Height = h = 7 cm

To find:

The curved surface area of the given cylinder.

Proof:

Curved surface area of a cylinder = 2πrh

Where:

1. π = $\frac{22}{7}$
2. r = 2.5 cm = $\frac{25}{10}$ cm
3. h = 7 cm

Substituting the values, we get:

= 2πrh

= 2 X $\frac{22}{7}$ X $\frac{25}{10}$ X 7

= 22 X 5

= 110 $cm^{2}$

Hence, the curved surface area of the given cylinder = 110 $cm^{2}$

Proved.
