A cone has a diameter of 30 in. and a slant height of 17 in.What is the approximate volume of the cone? Use 3.14 to approximate the value of PI.
Round your answer to the nearest tenth, if necessary.

Answers

Use the given formula :

V=\frac{1}3\pi r^2h=\frac{1}3\pi (\frac{D}2)^2h where D is the diameter.

By Pythagoras, h=√(17^2-(30/2)^2)=8\text{ in}

Hence V\approx\frac{3.14}3*15^2*8=\boxed{1884.0\text{ in}^3}

Sharon is 54 inches tall. tree in her backyard is five times as tall as she is. the floor of her treehouse is at a height that is twice as tall as she is. What is the difference in inches between the top of the tree and the floor of the treehouse?

Answers

First to solve this problem you are going to figure out how tall the tree is. So if Sharon is 54 inches and the tree 5 times the height she is you would do 54*5= 270. Next you go to find out how tall the floor of her tree house is. It says the floor is twice the height of her so you would do 54*2=108. Then the problem asks the difference between the top of the tree and the floor of the tree house. So 270-108=162. I hope this helped. :) Brainliest answer?
