Question

find volume if CSA is given 154m² & height is 3.5m​

Answer 1

Step-by-step explanation:

CSA of a cylinder is 154 m^2 and height is 3.5 m.

Then,

$csa = 2\pi \: rh$

$154 \: {m}^{2} = 2 \times \frac{22}{7} \times r \times 3.5m$

$r = \frac{154}{22} = 7m$

Hence the radius of the cylinder is 7 m.
