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 cone shaped pile is 732.67 feet³.

Step-by-step explanation:

A cone shaped pile of sawdust has a base of 20 feet diameter and height of 7 feet.

We have to calculate the volume of the pile.

As we know the formula to calculate the volume of a cone is

Therefore by putting these values in the formula we can get the answer

Volume of cone

                                 = 732.67 cubic feet.

So the answer is 732.67 feet³.

733.04 feet

Step-by-step explanation:

We are given the height and base diameter of a cone shaped pile.

We are to find the volume of this pile and we know the formula for the volume of the cone:

Volume of a cone =

Putting in the given values in the above formula:

Volume of cone-shaped pile = = 733.04 feet.

24

step-by-step explanation:

if it takes 8 pounds to make 12 divide 12 by 8 and you get 1.5, 1.5 x 16 = 24

(b) 240

step-by-step explanation:

first, we use the pythagorean formula using the given side lengths to find x. then we use x to find the side lengths. then we add the side lengths to find the perimeter.

pythagorean theorem formula:

a^2 + b^2 = c^2

(x - 20)^2 + (x - 40)^2 = x^2

x^2 - 40x + 400 + x^2 - 80x + 1600 = x^2

x^2 -120x + 2000 = 0

(x - 100)(x - 20) = 0

x - 100 = 0 or x - 20 = 0

x = 100 or x = 20

we see that the solution x = 20 must be discarded because it will give a negative side length and a side length of 0. the only valid solution is x = 100.

perimeter = sum of the lengths of the sides

perimeter = x + x - 20 + x - 40

perimeter = 3x - 60

replace x with 100.

perimeter = 3(100) - 60

perimeter = 300 - 60

perimeter = 240
