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

The capacity of a cylindrical water tank is 539 litres. If its height is 1.4 meter then find the radius of the base.​
natulia [17]

Answer:

350m

Step-by-step explanation:

  • capacity= volume/1000
  • but we know that volume of cylinder is πr²h so substitute it I'm the volume space
  • then substitute for π as 22/7, h as 1.4 , and also capacity as 539
  • 539= ((22/7)×r²×1.4)/1000
  • when you simplify you get r as 350m
