Find the diameter of a cone that had a volume of 56.52 cubic inches and a height of 6 inches

5.98 inches

Step-by-step explanation:

1. You have that the formula for calculate the volume of a cone is:

Where V is the volume, r is the radius and h is the height.

2. By definition, the diameter is twice the radius. Therefore, you need to solve for the radius:

3. Substitute values:

4. The diameter is:

b. 1.25 hr

step-by-step explanation:

if you have a constant speed of 60 mph, then you have a ratio between 60 mi. to 1 hr. dividing both sides by 60 we get the ratio

1 mi. to

then mult. both sides by 75 we get the ratio

75 mi. to

simplifying we get

75 mi. to

or 1.25 hr.
