Step-by-step explanation:
3² * pi * 4 = 113
113 / pi / 3²
gives you 4
this time the radius was squared correctly XD
Ok so here we can start of by finding the ratio of the original to the reduced which is 4:1. Then we can find out the width of the reduced which is 6. Finally, all you have to do is multiply 6 by 4 and you get the answer which is 24.
Answer: the rate of the car is 50 mph.
Step-by-step explanation:
Let x represent the rate of the car. If the rate of the bus is 10 miles per hour slower than the car, it means that the rate of the bus is (x - 10) mph.
Time = distance/speed
The car can travel 100 miles in the same time that it takes a bus to travel 80 miles. It means that the time taken by the bus to travel 100 miles is
100/x
and the time taken by the car to travel 80 miles is
80/(x - 10)
Since the time is the same, then
80/(x - 10) = 100/x
Cross multiplying, it becomes
80x = 100(x - 10)
80x = 100x - 1000
100x - 80x = 1000
20x = 1000
x = 1000/20
x = 50 mph
