Question

volumeof a cylinder =5346
ratio of radius and height=3:7
find radius and height​

Answer 1

Answer: r=9 ; h=21

Step-by-step explanation:

MARK ME AS BRAINLIEST PLEASE !!!

Volume of cylinder = πr²h

let r = 3x and h = 7x

πr²h=5346

22/7*3x*3x*7x=5346

on solving , we get

we get x³=27

thus , x=3

r=3x=3*3=9

h=7x=7*3=21

Answer 2

Answer:

Step-by-step explanation:

Let ratio be x

Ratio of radius and height is 3x:7x

5346=1/3*22/7*9(x^2)*7x

5346=22*3(x^3)

81 = x^3

x = 3root3

9root3=radius

21root3. = height
