Question

. Find the height of a cylinder whose radius is
14 m and total surface area is 1932 m²​

Answer 1

Answer:

Given :- 2πr (r+h) = 1932

2 × 22/7 × 14(14 + h) = 1932

88 (14 + h ) = 1932

14 + h = 1932 / 88 = 21.95

h = 21.95 - 14 = 7.95m

Answer 2

Answer:

Step-by-step explanation:

T.S.A of cylinder = 2π r(r + h)

1932= 2 * 22/7 * 14(14 + h)   (as 14 and 7 gets cancelled)

1932= 44*2(14 + h)

1932= 88*14 + 88h

1932= 1232 + 88h

1932 - 1232 = 88h

700=88h

h=700/88

h = 12.5m
