Exercise 7 Page 844

Use the formula for the volume of a cone.

28.1mm^3

Practice makes perfect

To calculate the volume of an oblique cone, we can use the following formula. V= 13π r^2 h Here r is the radius and h is the height of the cone. We are given that the height of the cone is 10.5mm and a radius is 1.6 mm. Let's substitute these values into the above formula and calculate the volume.

V=1/3π r^2 h

SubstituteII

r= 1.6, h= 10.5

V=1/3π ( 1.6)^2 ( 10.5)
