Answer:
The diameter is approximately 8.9 cm
Step-by-step explanation:
The circumference is given by
C = pi *d
28 = pi *d
Divide each side by pi
28/pi = d
We can approximate pi by 3.14
28 /3.14 =d
8.917 = d
The diameter is approximately 8.9 cm
Okay, to solve this we simply find 75% of the carton of paper, because 100%-25% = 75%
0.75(27) = 20.25
The carton of paper costs $20.25
