VOLUME OF THE 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
