Answer:
Step-by-step explanation:
formula for cylinder:V=πr2h
shape of the base: circle
formula for circle: A=πr2
radius: 6.5cm
height: 16cm
V=3.14x6.5^2x16
2122.64cm^3
12% less since faster
100%-12%=88%
88% of 4 min and 23 sec=
0.88 times 263 seconds=
=231.44=3 minutes and 50 seconds rounded
3 mins, 50 seconds
1. 600 / 900 = 260/x
234,000 / 600 = 390
the length = 390 feet
2. 100/20 = d/60
100/20 = 5
d = 60x5 = 300 feet
-2 is the function i think
