Marks: +1, -0

The circumference of the base of a 16 cm high solid cone is 33 cm. What is the volume of the cone in cubic centrimeters?

Solution:

Height of the cone = 16 cm
Circumference of the base = 33 cm
2πr = 33
r = 33 ×

7/{22}×1/2

r = 5.25 cm
Volume of the cone =

1/3×{22}/7×{525}/{100}×{525}/{100}×16

{97020000}/{210000}

= 462
