Answer:
D
Step-by-step explanation:
The formula for calculating circumference (C) are
C = 2πr ( r is the radius ) → D
or
C = πd ( d is the diameter )
Answer:
x = 4
Step-by-step explanation:
1/5x + 4/5 = 8/5
Multiply each side by 5 to get rid of the fractions
5(1/5x + 4/5) = 8/5 *5
x+4 = 8
Subtract 4 from each side
x+4-4 = 8-4
x = 4
Set up a proportion...
<u>(1/3)</u> = <u>x</u>
<u /> 2 12
Cross multiply to get 2x = 4. So x = 2 loaves of bread.
