The formula for a circle’s circumference (circle’s unique perimeter) is pi * diameter.

However, since we have a semicircle (half of the circle), our formula would 1/2 * pi * diameter, or just pi * radius.

Set up an equation and solve.

10.28 = pi * radius.

r = (10.28)/pi

Natali5045456 [20]

The answer is 9

Explanation:

We know the total amount of spaghetti sauce is 20.5 cups; additionally, each container can be filled with a maximum of 2.5 cups of this sauce. In this context, the process to know the number of containers Mr. Rush needs to store all the sauce is to divide the total amount by the amount each container can hold.

20.5 cups of sauce ÷ 2.5 cups per container = 8.2 containers

This means 8 containers can be completely filled and a ninth container is required to hold the small amount of the sauce missing (0.2)

Order the values from least to greatest
melomori [17]
1.) -4 , -2 , 1 , 3 , |-5|

-4 and -2 are first because they are the least, then 1 and 3 are next. The absolute value of -5 is last because it has the greatest value, 5. (The absolute value of a negative number is the same number but positive)

2.) |8| , -5 , 0 , |-9| , 11

The absolute value if 8 is first because it has the least value, -8. (The absolute value of a positive number is the same number but negative) Then -5 and 0 are next. The absolute value of -9 is next because it is actually 9, and 11 is last because it has the greatest value.
