The volume of a cylinder is 1200cm3 and the area of its base is 150cm2. Find the height of the cylinder.
80.00cm
8.00cm
0.80cm
0.08cm
Explicação
Vol. of cylinder = \(\pi r^2h\) = 1200cm2
Area of base = \(\pi(r^2)\) = 150cm2
h = \(\frac{\text{volume of cylinder}}{\text{base area}} = \frac{1200}{150}\)
= 8.00cm
Area of base = \(\pi(r^2)\) = 150cm2
h = \(\frac{\text{volume of cylinder}}{\text{base area}} = \frac{1200}{150}\)
= 8.00cm
