Equation for Volume of a Cone

Equation for Volume of a Cone Volume is an amount of 3-dimesional space occupied by an object. The equation or formula for volume of a cone is v = ( 1/3) x r2h. Here, the base is the circle. We know r is the radius of the base of the cone and h is the height of the cone. Example 1: Find the volume of the cone with radius 9 cm and height 7 cm. Solution: From the problem we can write, Radius = r = 9 cm and height = h = 7 cm. We know the formula to find the volume of a cone That is v = (1/3) x r2h Now we can plug the values in this formula, then we can write Volume = v = ( 1/3)x 22/7x 92x 7. From this we can write, v = 22 x 27 = 594 cubic cm. Example 2: Find the volume of the cone with radius 3 cm and height 14 cm. Solution: From the problem we can write, Radius = r = 3 cm and height = h = 14 cm. We know the formula to find the volume of a cone That is v =(1/3 )x r2h Now we can plug the values in this formula, then we can write Volume = v = ( 1/3)x 22/7x 32x 14. From this we can write, v = 22 x 3 x 2 =132 cubic cm.
