Given : A cone has a diameter of 70mm and a height of 100mm.
To Find : the volume of the cone to the nearest whole number.
Solution:
Diameter of cone = 70 mm
Radius = Diameter / 2
=> Radius of cone r = 70/2 = 35 m
Height of cone h = 100 mm
Volume of cone = (1/3) πr²h
= (1/3) (22/7) (35)² * 100
= 385000/3
= 1,28,333.33 mm³
= 128333 mm³
