5. Skateboarding has become a popu construction ramps in some o quarter-cir the centers. ecome a popular sport. The parks department is thinking of n some of the local playgrounds. A \"half-pipe\" ramp is formed by two mps, each of which is 10 feet high, plus a flat space 20 feet long between !\"..: iar 10 ft. 10 ft. 20 ft. a) Find the distance a skater travels from the top of one ramp to the top of the other. Round to the nearest hundredth.

Solution

a) radius of each circle r=10ft

distance scater travells=((_/2)*10)+20+((_/2)*10)

distance scater travells=20+(10)

distance scater travells=51.42 ft

b)itakes 8 second =(8/60)min

speed of skater =51.42_/(8/60)

speed of skater =385.62 feet per minute
