We can use the formula for the volume of a cone.
V=1/3 B h
Here, B is the area of the base and h is the height of the cone. Since the base is a circle, the area of the base will be equal to π r^2, where r is the radius.
V= 1/3 π r^2 h
We are given that the height of the cone is 9 yards and the diameter of the base is 7 yards. Note that if we divide the diameter by 2, we get the radius of the base.
r=7/2= 3.5yd
Let's substitute r= 3.5 and h= 9 into the formula and calculate the volume.
