27 is 54% of 50! You can set up fractions (proportions) as 27/50 = blank/100!
Well how do you get to 50 to 100? You multiply by 2! And whatever you do to the bottom you must do to the top! So 27 times 2 is 54!
Just the first one, r is 4x+2, and h is 5x+4, plug them into the formula pls
Answer:
2
Step-by-step explanation:
15+-13 = 2
An angle adjacent to BOC would be COD or BAC.
c = circumference
pi = 3.14
r = radius = 9 inches
d = diameter
c=pi*d
The radius is half of the diameter, d = 2r. Then d = 2*9=18.
plug into equation. c= pi*d = 3.14*18
round accordingly and you may want to include that the measurement you end up with is in inches.
