Question

The radius and height of a cylinder are in the ratio 3:4 and it's volume is 5346 cm cube find its radius

Answer 1

I think it is helpful for you

Answer 2

volume of the cylinder = $\pi r^{2} h = 5346$

as the ratio of radius and height is 3:4 lets take radius as 3r and height as 4r

$\pi *3r*3r*4r =5346 \\ \pi r^{3} = \frac{5346}{3*3*4} \\ r^{3} = \frac{5346*7}{3*3*4*22} \\ r^{3} =47.25 \\ r = 6.87cm$
