Answer: A. 30
Step-by-step explanation:
The formula for the area of a circle is pi*r^2, where r is the radius of the circle.
900pi = pi*r^2
Divide both sides by pi.
900 = r^2
Square root both sides.
r = +/- 30.
Since the radius cannot be negative, the answer is 30 units.
The answer is C The distance between the points (15,6) and (21,22)
-6r+5
the two like terms are the ones with R. combine -4r and -2r to get -6r
The question is asking you how many times 6 can go into 36... So 6 goes into 36, 0.16/ 0.66 times
So Basically, 6 divided by 36 = 0.16
The answer to this equation is 1412 or 21-15
