The answer is c!!!!!!!!!!!!!!!!!!!!!!!!
Step-by-step explanation:
Multiply the radius by 2 to get the diameter. Multiply the result by π, or 3.14 for an estimation. That's it; you found the circumference of the circle
And then for diameter you have to Multiply the diameter by π, or 3.14. The result is the circle's circumference.
You have to round it to the nearest hundreds
4.5X+1450=C
X represents the amount of square feet
C represents the total cost
65 people=20 minutes
20*3=60 minutes which is 1 hour
65*3=195 people per hour (This is the rate per hour)
195*6=1,170 people per six hours
