Question

Find the curved surface area of a cylinder with radius 7 cm and height 10 cm.​

Answer 1

Answer:

curved surface area of a cylinder  = 440cm²

Step-by-step explanation:

Given :-

radius = 7 cm

height = 10 cm

curved surface area of a cylinder   =  2π × r × h

∴curved surface area of a cylinder =  2×22/7 × 7 × 10

∴curved surface area of a cylinder =2 x 22 × 10 = 440cm²

Answer 2

Answer:

440 cm square

Step-by-step explanation:

radius=7 cm

height=10 cm

pi=22/7

curved surface area of a cylinder=2pirh

                                 =2*22/7*7*10

                                 =22*2*10  

                                 =22*20

                                 =440cm^2

curved surface area= 440 cm square
