This requires you to find the volume of the cone.
The volume of a cone is 1/3 the area of the base (a circle) times the height of the cone, or 1/3(3.14)r^2 * h.

The radius of the base is 7.5/2 or 3.75.

V = 1/3(3.14 * 3.75^2) * 3.5

V = 1/3(44.16) * 3.5

V = 1/3*154.56

V = 51.5 cm^3 of feed

Answer:

51.5\ cm^{3}

Step-by-step explanation:

step 1

Find the volume of a cone

we know that

The volume of a cone is equal to

V=\frac{1}{3}\pi r^{2}h

we have

r=7.5/2=3.75\ cm -----> the radius is half the diameter

h=3.5\ cm

substitute the values

V=\frac{1}{3}(3.14)(3.75^{2})(3.5)=51.5\ cm^{3}
