If she rides her bike 18 km per hour
then it will take 4 hours to travel 72 km (72÷18)
the answer is 4
We need to solve for the radius. So using the "formula" for the surface area, we have
900*pi ft^2 = 4*pi*r^2 divide by pi
900 ft^2 = 4*r^2 divide by 4
225ft^2 = r^2 take the square root of each side
15 ft = r
This should give you tools to answer all the questions.
