Answer:

x=1/3

Subtract 3 from both sides

3x=1

Divide both sides by 3

x=1/3

A cone-shaped pile of sawdust has a base diameter of 20 feet, and is 7 feet tall. Find the volume of the pile.
Phoenix [80]

Answer:

About 733.04 feet


Step-by-step explanation:

Volume of Cone is given by the formula  V=\frac{1}{3}\pi r^2h

Where

  • V is the volume
  • r is the radius
  • h is the height

Given height as 7 ft, and radius is 10 feet (Radius is half of diameter(20))

<em>Substituting into formula, we get:</em>

V=\frac{1}{3}\pi r^2 h\\V=\frac{1}{3}\pi (10)^2(7)\\V=\frac{700\pi}{3}\\V=733.04 ft
