First find the volume of the cylinder v = pi* r^2 * h
Then find the volume of the cone V = 1/3 * pi* r^2 * h
Then compare your two numbers.
He went around 24 times and 4 times is a mile so 24/4 will tell us how many miles he biked. He biked 6 miles in thirty minutes. The formula distance = rate(time) will tell you how fast he is going.
6 = r(1/2) divide each side by 1/2 (The time has to be in hours)
12 = r
So he was going 12 miles an hour.
Answer:
