Question

The radius and height of a cylinder
ars in the ratio 4:7 and its volume
is 1188cm3 find its radius.​

Answer 1

Answer:

1.5

Step-by-step explanation:

let the radius of the base and height of the cylinder be 4xcm and 7xcm respectively then,

volume=1188cmcube

( volume of a cylinder = πrsquareh )

22/7×4x×4x×7x=1188

22×4x×4x×x=1188

22 x 16x3=1188

352 × x3=1188

x3 = 1188/352

x3 = 3.37

x = 1.5
