CIRCUMFERENCE OF THE CIRCLE
The CIRCUMFERENCE of a circle is the total length of the outer periphery(boundary) of the circle.
If radius of the circle = r
Then, Circumference of the circle...
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
