A cone and its dimensions are shown in the diagram. Which measurement is closest to the volume of the cone in cubic inches?

Answers

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.

The answer is b because 6(4x+3y) would be 6*4=24x then 6*3=18y

An equaivalen expression to 24x + 18y is  6(4x + 3y).

What are GCF and distributive property?

The GCF of two or more than two numbers is the highest number that divides the given two numbers completely.

We also know that distributive property states a(b + c) = ab + ac.

Given, An expression 24x + 18y.

Now HCF of 24 and 18 is 6 so we can takeout one multiple of 6 from the expression as,

24x + 18y.

= 6(4x + 3y).

We can not take x or y common because both the terms do not have them.
