Achildren's wading pool is in the shape of a right circular cylinder, and has a diameter of 6 feet. the pool is filled to a uniform depth of 1.5 feet.
which of the following values is closest to the volume of
water in the pool, in cubic feet?
a. 28
b. 42
c. 57
d. 67
e. 133

B) 42

Step-by-step explanation:

The area of a cylinder is pi*r^2*h where r is the radius and h is the height. Plugging in 3 for the radius(radius=diameter/2) and 1.5 for height you get area=pi*9*1.5. Assuming pi as 3.14 you get 3.14*9*1.5 which is 42.39 which is approx. 42.

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
