By definition, the volume of a cone is given by:

Where,
r: radius of the circular base
h: height of the cone
Let's define a variable:
x: diameter of the base
We have then that the radio is:

The height is:

Substituting values:

Rewriting:
Answer:
An expression that represents the volume of the cone, in cubic units is:
Hi,
A is the answer as : -2+2 = 0 and 5 -5 = 0
Answer:
3/4 miles per minute
Step-by-step explanation:
To get speed in miles per minute, just divide distance/time
1/4 mile / 1/3 minute = 3/4 miles per minute
If you want miles per hour, you'll have to convert minutes to hours.
3/4 miles/minute * 60 minutes/hour = 45 miles/hour
Answer:
The radius of the circle r=12.
The area of a circle is 144π.
Step-by-step explanation:
The radius of the circle is r where 2πr=24π, r=12.
The area of a circle with radius 12 is
A=πr², A=π12², A=144π.
