Question

the radius and height of a cylinder are in the ratio 14 : 5 and its volume is 308 cm cube find it's radius . PLEASE SOLVE IT​

Answer 1

The radius of the cylinder is 6.5 cm

Step-by-step explanation:

Given: Radius to Height ratio = 14 : 5, Volume = 308 cm cube

Assumption: From the ratio given above,

Let 14x be the radius of the cylinder, Let 5x be the height of the cylinder

Volume of the cylinder is R2H  

Therefore, R2H =308

Value of = 22/7

Hence, 22/7 x  14x x 14x x 5x = 308

Therefore x3 = 1/10

x = 1/2.15

Therefore Radius of the cylinder is 6.5 cm
