Question

in each example given below, radius of base of a cylinder and its height are given. then find the curved surface area and total surface area. r=7cm, h=10cm​

Answer 1

Answer:-

CSA(Curved Surface Area) = 440 square cm,

TSA(Total Surface Area) = 748 square cm.

Step-by-step explanation:

Height of the cylinder(h) = 10 cm

Radius(r) =7 cm

Curved Surface Area = 2πrh

= 2×22×7×10

7

= 2×22×10

= 44×10

= 440 square cm.

Total Surface Area = 2πr(r+h)

= 2×22×7(7+10)

7

= 2×22×7(17)

7

= 2×22×17

= 44×17

= 748 square cm.
