Harold uses a cone shaped feeder, with a diameter of 7.5 centimeters and a height of 3.5 centimeters, to feed his tropical fish.
How many cubic centimeters of feed can this feeder hold?
Use 3.14 for pi.
in the meantime, why didn't you just look up the formula for the volume of a cone?
v = 1/3 pi r^2 h = 1/3 * 3.14 * (7.5/2)^2 * 3.5 = 51.52 cm^3

The aspherical container has a radius of 1 yard. It is filled with liquid fuel that costs $10 per cubic yard.
What is the total value of the fuel in the container?
Use 3.14 for π.

To find the volume of the cone-shaped feeder, we can use the formula:
V = (1/3) * π * r^2 * h
where V is the volume, π is approximately 3.14, r is the radius (half the diameter), and h is the height.
First, let's find the radius (r) of the cone-shaped feeder:
Given a diameter of 7.5 centimeters, we can divide it by 2 to get the radius:
r = 7.5 cm / 2 = 3.75 cm
Next, let's substitute the values into the formula:
V = (1/3) * 3.14 * (3.75 cm)^2 * 3.5 cm
V = (1/3) * 3.14 * 14.0625 cm^2 * 3.5 cm
V = (1/3) * 3.14 * 49.21875 cm^3 * 3.5 cm
V = 0.3395 * 49.21875 cm^3
V ≈ 16.724 cm^3
Therefore, the cone-shaped feeder can hold approximately 16.724 cubic centimeters of feed.
