The circumference of a circle of radius 
is
So, in your case, the circumference is
The circumference is actually the length of the "perimeter", so the answer to questions 1 and 2 looks the same actually
First you have to get the number on the right 40 to equal 100 so do 40x2=80- +40x1.5= 100
Then do the same thing to the first number 8 so 8x2=16+8x1.5=20
then you have 20/100 right so then that number over 100 is the percent that you get ^-^ 20%
Answer: 63/2π
Step-by-step explanation: C=πd
63=πd
D=63/π
r=1/2d
1/2×63/π=<u>63/2π</u>
Answer:
when y rename a fraction, you are finding fraction that have the same value but have different name. these are known as equivalent fraction you can rename fraction million of different ways...As long as you multiply numerator and denominator by same number, you will get and equivalent fraction...
Step-by-step explanation:
for example :5/2
5×2/2×2 , 5×3/2×3 , 5×4/2×4 , 5×5/2×5
ANSWER OF THESE EQUIVALENT NUMBERS ARE :
10/4 , 15/6 , 20/8 , 24/10 ....
