Acone-shaped pile of sawdust has a base diameter of 20 feet, and is 7 feet tall. find the volume of the pile.

Volume of pile is 732.6 cubic ft

Step-by-step explanation:

We are given a cone-shaped pile of sawdust, and we have to find the volume of this pile

Base diameter = 20ft

height, h = 7ft

Using the formula for Volume of Cone: πr²h/3

Where r is the radius of base:

First find out radius from diameter:

r = = 10ft

putting values fo radius, r and height h, in volume formula:

π = 3.14

v =  πr²h/3 =

v = 732.6

733.04 feet

Step-by-step explanation:

We know that a cone-shaped pile of sawdust has a base diameter of 20 feet, and is 7 feet tall.

We know the formula for the volume of the cone:

Volume of a cone =

So substituting the given values in the above formula:

Volume of cone-shaped pile = = 733.04 feet.

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
