What is the volume of the cone shown below?

C. 96π cubic units

Step-by-step explanation:

The volume of a cone can be found using the following formula.

The radius of the cone is 4 units and the height is 18 units.

r= 4 units

h=18 units

Substitute the values into the formula.

First, evaluate the exponent, 4 units^2.

4 units^2= 4 units * 4 units= 16 units^2

Next, multiply 16 units^2 and 18 units

16 units^2*18 units= 288 units^3

Next, multiply 1/3 and 288 units^3, or divide 288 units^3 by 3.

1/3 * 288 units^3 =96 units^2

288 units^3/3=96 units^3

This can be rewritten as:

The volume of the cone is 96π cubic units. Therefore, C is the correct answer choice.

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.
