Jordan wrote the following description. Three fewer than one fourth of x is 12. Write an equation to represent the description??
VMariaS [17]

Answer:

1/4x - 3 = 12

Step-by-step explanation:

When it says "three fewer," it means subtract three from one fourth of x. "Is" always means the equal sign. Knowing this, we get the equation:

1/4x - 3 = 12

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
