Question

the radius and height of a cylinder are in the ratio 7 : 5 and its volume is 6160 cm³. find its radius​

Answer 1

Answer

step by step explanation

volume = π r2h

= 22/7 ×7x×7x×5x

6160= 22×35x^3

35x3= 6160÷22

35x^3= 280

x^3 = 280/35

x^3= 8

X=2

now, radius = 7 ×2

radius = 14

i hope it will help you to solve the problems.

Answer 2

Answer:

the radius will be 14cm
