What do you mean? Your answer wouldn't be 3.14, but you would need to use 3.14 in order to find the circumference of a circle.
12
change the mixed numbers to improper fractions before dividing
1 
= 
and 15 
= 
divide contents of box by a serving
÷
change ÷ to × and turn the second fraction upside down
= × 
= 
= 12.26666 = 12 complete servings
The domain of t is the years the account is active: 0 - 6 years. The domain of t sets the range of A.
When t = 0 A = 15,000.00
when t = 6 ; A = 18,979.79
So it's answer D.
First, change the mixed fraction into improper fraction
1 1/7 = 7/7 + 1/7 = 8/7
(4/7)/(8/7)
To solve, flip the second fraction, and change the division into multiplication
(4/7)/(8/7) = (4/7) x (7/8)
Multiply, and simplify
(4/7) x (7/8) = 28/56, or 1/2
1/2 is your answer
hope this helps
Find the area of the circle:
Area = 3.14 x 12^2 = 3.24x144 = 452.16 cm^2
The sector is 60 degrees.
Multiply the area of the circle by the fraction of the sector:
452.16 x 60/360 = 75.36 cm^2
