Given the circle above, what is the length of radius r to the nearest tench of an inch? use 3.14 for pi.

3.1 in

Step-by-step explanation:

for the given circle the following ratios are equal

= , hence

=

cross- multiply

2πr × = 8π ( divide both sides by 2π )

r = 4

multiply both sides by 12 and divide by 5π

r = = 3.1 ( to the nearest tenth )

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m
