Answer:
36 minutes
Step-by-step explanation:
We can write a ratio
2 laps 9 laps
------------- = --------------
8 minutes x minutes
Using cross products
2x = 8*9
2x = 72
Divide by 2
2x/2 = 72/2
x = 36 minutes
I think it's 115
180-65= 115=<BCD
In the circumference formula given d is the diameter which is 2 times r ( r is the radius)
R is given as 6 feet, diameter = 2 x 6 = 12 feet.
Circumference = 12 feet x 3.14 = 37.68 feet
