Question

If the radius and HT of cylinder are in the ratio 5:7and volume is550cmfind it's radius

Answer 1

radius= 5 cm. If it has helped you then mark me as brainliest.

Answer 2

let the ratio=x

then,radius=5x

height=7x

$\pi {r}^{2} h = 550$

22/7x×5x×5x×7x=550

$22 \times 25 {x}^{3} = 550$

${x}^{3} = 550 \div 22 \times 25$

${x}^{3} =1$

$x = \sqrt[3]{1}$

$x = 1$

then radius=5cm and height=7cm
