VOLUME OF THE CONE

Cone

If, r=radis of the cone

h= perpendicular height

Then,

1)The volume of the cone =( 1/3 )πr²h

Ex- If,r=14 cm, h=15cm, then

1)The volume of the cone =( 1/3 )πr²h

=(1/3)x(22/7)x14x14x15

=22x2x14x5

=3080 cubic cm

=2640 square cm

2)Total surface Area of cone= πr(r+l)

=22/7x28(28+30)

= 22x4(58)

=5104 square cm
