What is the radius of the base of a cylinder with a volume of 36π cm3 and a height of 4 cm?
| February 16, 2021 | education
Since the volume of the cylinder is: V = Sb * h, then Sb = V / h = 36 * p / 4 = 9 * p cm2.
We define the radius of the circle at the base through the area of the base of the cylinder.
Sosn = n * R ^ 2.
R2 = Sb / n = 9 * n / n = 9.
R = 3 cm.
Answer: the radius of the circle is 3 cm.
