Question

Volume up 1056cm3. it is 21 cm high find the radius of the cylinder, solution

Answer 1

Given that :

Volume of cylinder = 1056 cm^3 and height of cylinder = 21 cm

As we know that :

Volume of cylinder = πr^2h

According to the question :

πr^2h = 1056

=> 22/7×r^2×21 = 1056

=> r^2 = (1056×7)/(22×21)

=> r^2 = 16

=> r = √16 = 4 cm

So, the radius of cylinder will be 4 cm ✔
