The formula for circumference is 2 x PI x r
Using the circumference we can find the radius:
50.24 = 2 x PI x r
Multiply 2 by PI:
2 x 3.14 = 6.28
50.24 = 6.28 x r
Divide both sides by 6.28:
R = 50.24 / 6.28
R = 8
The radius is 8 units.
Answer:
A
Step-by-step explanation:
So you can’t factor out the variables since one is d and the other is a. If they were the same letter you could factor them out as well
The only number that goes into both 9 and 12 is three
So divide by three essentially and take it out and place is next to the rest of the equation that is now in parenthesis
3(3d^3 - 4a^2)
Answer:c
