Answer:
The radius of the new cheese ball formed is approximately 6.603 inches.
Step-by-step explanation:
We are given the following in the question:
Radius of three cheese ball = 2 inches, 4 inches, and 6 inches
They were combined to form a new cheese ball.
Thus, we can write
Volume of three cheese balls = Volume of new cheese ball.
Let r be the radius of new cheese ball.
Volume of sphere =
Putting values, we get:
Thus, the radius of the new cheese ball formed is approximately 6.603 inches.
Linear because you are adding the same amount every time
This would be 45.9
Get a calculator or try long division :-)
First, you drive 123km per day, and they ask for in a week.
There are 7 days in a week, we have to multiply 123 by 7, which equals 861.
=km per week 861
Now, we need to find out how much cost the gas. Gas cost 1.10 euros per-liter, and this problem wants us to assume that 1euro = 1.26 dollars.
So, we divide 1.10 by 1.26 which is 0.87.
=gas cost 0.87 per liter.
Next, this person goes 31.0 mi/gal per stop.
To get the answer we need to divide 861 the full distance in a week and divide it by how many stops nee to be made which is each 31 mi/gal.
So, 861/31 = 27.77 and now we times 0.87 by 27.77 to get gas cost.
=24.16
