Question

The radius and height of a cylinder are 7cm and 20cm,then the lateral surface area of cylinder is ? (hint:use Lsa of cyinder) ​

Answer 1

Step-by-step explanation:

Given,

=> Radius of Cylinder = 7 cm

=> Height of Cylinder = 20 cm

As we know that there is a Formula to find out Lateral Surface Area.

=> L.S.A = 2πrh

=> L.S.A =( 2 x 22/7 x 7 x 20) cm^2

=> L.S.A = 880 cm^2

Answer 2

Answer:

Radius of the cylinder is 7 cm

Height of the cylinder is 20 cm

As we know that there is a formula to find the LSA of cylinder

$\: lsa = 2\pi \: r \: h \\ \: \: = \: 2 \times 22 \div 7 \times 7 \times 20 \\ = 880 {cm}^{2}$

Hope it helps you...
