Question

what is the height of right circular cylinder whose curve surface area is 154 cm square and radius is 7 cm. *​

Answer 1

Answer:

3.5 cm

Step-by-step explanation:

Curved Surface area of cylinder = 2 × 22/7 × r × h

Given, C.S.A. = 154 cm², radius (r) = 7 cm.

=> 154 = 2 × 22/7 × 7 × h

=> 154 = 44 × h

=> h = 154/44

=> h = 3.5 cm
