Question

You have a can that is in the shape of a cylinder. It has a volume of about 1,728 cubic centimeters. The height of the can is 22 centimeters. What is the approximate length of the radius? Use 3.14 for pi.

Answer 1

HI,

Volume of a cylinder: V = π × r² × h

We know: h, V
We search: r

If we transform the formula:
r² = V/(π × h) so r = ✓(V/(π × h))

r² = 1 728 / 3.14 × 22
r² = 1728 / 69,08
r² ≈ 25 cm

So r = ✓25 = 5 cm
