Question

(ii) The lateral surface area of a right circular cylinder with the base radius 7 cm and height 10 cm is

Answer 1

Answer:

Pls Mark as brainliest if it helps.

lateral surface area = 2 * pi * r * h

  =>  2 * 3.14 * 7 * 10

 => 140 * 3.14   = 439.6

or

22/7 * 2 * 7 * 10   =>  44 * 10 = 440

Answer 2

Step-by-step explanation:

Radius=7cm

Height=10cm

Lateral surface area of cyclinder=2πrh

=2×22/7×7×10

=440cm square.
