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

Tina wants to save money for school. Tina invests $400 in an account that pays an interest rate of 7.5%.
Over [174]
Here's the given:
P=$400
i=7.5%
A=$8500

The formula used for this problem is:
A = P(1+i)^t

Manipulating the equation to arrive at t, we have:
t = ln(A/P) / ln(1+i)

Plugging in values:
t = ln($8500/$400) / ln(1+0.075)
<span>t = 42.26 years</span>
