Answer:
25.12 millimeters is your answer.
Step-by-step explanation:
Circumference can be solved by using the equation:
c = 2πr or c = πd
Note that diameter (d) is equal to 8. Plug in 8 for d.
c = (8)(π)
Also note that π = 3.14. Multiply
c = (8)(3.14)
c = 25.12 millimeters.
25.12 millimeters is your answer.

Step-by-step explanation:
8/3 cups of sugar is needed to make 16 cookies.
For 90 cookies, we will need 8/3 * 90/16 = 15 cups of sugar.
The inequality would be 3.1h + 2.3b ≥100
Step-by-step explanation:
Earning of Tammy for each hour of work= $3.1
Total hours she worked= h
Earning for picking each bushel of apple= $2.3
Total bushel she picks= b
Her goal = minimum of $100
Hence total earning from working= earning from each hour* no of hours worked
Total earning= 3.1h
Similarly, total earning from picking up apple bushels= earning from picking one bushel*no of bushels picked
Total earning= 2.3b
According to question total earning must be greater than $100
Hence, 3.1h + 2.3b ≥100
Answer:

Step-by-step explanation:
we know that
The area of the circle is equal to

where
D is the diameter of the circle
Solve for D
That means-----> Isolate the variable D
Multiply both sides by 4 to remove the fraction

Divide both sides by π

square root both sides

Rewrite

Simplify

40+60=100
I hope this helps^^
