Question

find the volume of cylinder whose ( take π = 22/7 ) r=2.8 ,h=15 cm​

Answer 1

Volume of cylinder = pi*r^2*h

= 22/7*2.8*2.8*15

= 1848/5 cm^3

= 369.6 cm^3

Answer 2

$\huge\underline\mathcal{Solution}$

Volume of cylinder

$\implies\sf πr^2h$

$\implies\sf \frac{22}{7}×2.8×2.8×15$

$\implies\sf 22×0.4×2.8×15$

$\implies\sf 369.6cm^3$
