1 Horse in a Race (1 Horse Race)
Congratulations! You already have. h = S+r
r = 60 m/h t = 2 h D = r t = (60m/h) x (2h) = 120 mi
If v = r * h then> r = v / h
The area of a cylinder is 2 x pi x the radius (r) x (radius + height) 2.pi.r.(r+h) = 2x3.143x1(1+5) = 6.286(6) = 37 square cm or what ever the units are ( you don't say what the units are)
It depends on what "a r equals 8" means.

This is a Ditloid The answer is 7 Hills of Rome.
The volume of this cone is 301.6 units3
Make r the subject of the formula pi*r2*h = V r = the square root of V/pi*h
It's not stated in the problem, but I'm going to assume that Container 1 is full of milk, and that milk is being poured into Container 2. The volume of Container 1 is (1/3)*pi*h*r2. We know r=4 and h=9, so the volume is 48*pi cubic units. The volume of Container 2 is pi*h*r2. We know r=5, so the volume becomes pi*h*25. We want to find h so that the volume of Container 2 is the same as the volume of Container 2, or: pi*h*25 = 48*pi, or h = 48/25 = 1 23/25 units.
