Answer:
6
Step-by-step explanation:
A = pi r^2
C = 2 pi r
A = B (area)
3C = B
sub C = 2 pi r into 3C = B, and A = pi r ^ 2 into B
3 (2 pi r) = pi r ^ 2
6 pi r = pi r^2
( divide both sides by pi )
6r = r^2
r^2 - 6r = 0
r(r-6) = 0
r = 0 or r-6 = 0
radius can not be 0 , therefore r = 6
hope this makes sense, might be little confusing sorry!
There are 7 nickels, 9 dimes, and 16 quarters. If you do the math 7 nickels equals 35 cents, 9 dimes equal 90 cents, and 16 quarters equals $4.00, which all adds up to $5.25. Also the numbers follow the rules because 7 is two less than nine and 16 is 9+7.
