Question

The circumference of the base of a cylinder is 22 cm and its height is 10 cm. find its lateral surface area.​

Answer 1

Answer:

Circumference = $2\pi r = 22cm^{2}$

Lateral surface area = $\\2\pi r \times h \\ \\ = 22 \times 10 = 220cm^{2}$

Answer 2

Answer:

The lateral surface area is $220 cm^{2}$

Step-by-step explanation:

Lateral Surface Area: It comprises the entire surface area, omitting the top and bottom portions.

Given: circumference of the base of the cylinder is $22cm$ and height is $10cm$.

To find: the lateral surface area.​

The formula of lateral  lateral surface area (A).

A=$2\pi r$

$22=2\pi r$

$22=2*\frac{22}{7}*r$

radius (r)=$3.5cm$

And

height (h)=$10 cm$

Lateral surface area=$2\pi rh$

Lateral surface area=$2$×$\frac{22}{7}$×$3.5$×$10$

=$220 cm^{2}$

Hence, the lateral surface area is $220 cm^{2}$
