Answer:
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.
