Question

Q30. If the C,S,A of a right circular cylinder is 44m2 and r=0.5m then height .
(a) 1m (b) 0.5m (c) 2m (d) 1.5m​

Answer 1

Answer:

If the C.S.A. of a right circular cylinder is $44m^2$ and $r = 0.5m$ then height 15m.

Step-by-step explanation:

Given:

R=0.5m

$CSA=44 m^2$

Let's assume height be h

$2\pi rh = 44 m^2$

$2 \times \frac{22}{7} \times 0.5 \times h = 44\\ 44 \times0.5 \times h = 308 \\ 22 h= 308\\ h=\frac{308}{22} = 15 m$
