Step-by-step explanation:
0.2:1
I divided 3 by 15 and got 0.2 and then divided 15 by 15 to get one
20 Cubic Inches^3.
Explanation:
The volume of a cone is Pi*R^2*H*1/3
We know the height, but we are given the diameter instead of radius. So divide 5.625 by 2. You get 2.8125.
Plug everything into the formula.
Pi*2.8125^2*7.5*1/3
(The ^2 means squared, or to the second power)
You get a number close to 20. Since we don’t know Pi, and we are not given a substitute for Pi, we make the answer in terms of Pi.
20 Cubic Inches^3.
Also, people who don’t know the answers to questions shouldn’t just put a random answer for the points. It’s unfair.
