Answer:

$Difference = 5757\ feet$

Step-by-step explanation:

Given

$Highest\ Point = 5764\ feet$

$Lowest\ Point = 7\ feet$

Required

Determine the difference between the points

The difference is calculated as follows:

$Difference = Highest - Lowest$

$Difference = 5764\ feet - 7\ feet$

$Difference = 5757\ feet$

Three people share half a pizza evenly. What fractional part of the original pizza does each one get?

beks73 [17]

Answer:

The fractional part of the original pizza is $\frac{1}{6}$

Step-by-step explanation:

Let

x-----> the original pizza (complete pizza)

we know that

Half a pizza represent ------> $\frac{x}{2}$

Divide half a pizza by three people

$(\frac{x}{2})/3=\frac{x}{6}$

therefore

The fractional part of the original pizza is $\frac{1}{6}$

What is the volume of a right circular cone if the circumference of the base is 125.6 ft and the height is 75 ft.?

Eddi Din [679]

Answer:

Hence the volume of the cone is 31384.52 cubic feet

Step-by-step explanation:

We must first need to understand how the volume of a cone is calculated.

It is simply calculated by multiplying the base area of the cone by the height, and dividing the result by 3.

This is :

Volume of cone = $\frac{\pi r^2 h}{3}$

we are not given the base area of the cone. However, we are given the circumference from which we can get the radius of the base.

Circumference =

$2 \pi r=125.6ft\\r =125.6/2 \pi=19.99ft$

hence the volume of the cone is

$\frac{\pi (19.99)^2 75}{3}=31384.52ft^{3}$

Hence the volume of the cone is 31384.52 cubic feet
