A cylindrical grain bin has a radius of 7 feet and a height of 25 feet. How many cubic feet of grain can the bin hold
dimaraw [331]

Answer:

1225π

Step-by-step explanation:

The question concerns the volume of the cylinder.

The formula of the volume is:

V=\pi r^{2} h, where r is the radius and h is the height.

Plugging the given numbers into the formula, we find that:

V=\pi * 49 * 25=1225\pi

The result - 1225π shows that the cylinder can be filled fully with that given amount.

14. A plane traveled from California and back. It took one hour longer on the way out than it did on the way back. The plane's a
kow [346]

Answer:

  C.  7 hours

Step-by-step explanation:

Let the time for the trip out be represented by t. Then the time for the return trip is t-1. The distance was the same for both trips, so we have ...

  distance = speed × time

  300t = 350(t -1)

  300t = 350t -350 . . . . eliminate parentheses

  350 = 50t . . . . . . . . . . add 350-300t

  7 = t . . . . . . divide by 50

The trip out took 7 hours.
