Question

A cylinder has a diameter of 15cm and a volume of 350cm3. What is the height of the cylinder? ( Take pi = 3.142 )

Answer 1

Step-by-step explanation:

Diametre = 15 cm

therefore radius = 7.5 cm

Volume = 350 cm^3

we know that,

Vol(Cylinder) = π.r^2.h

             350 = 3.142 X (7.5)^2 X h

             350 = 176.7375 X h

             350 / 176.7375 = h

Therefore, h = 1.980 cm

therefore the height of the cylinder is 1.980 cm
