Answer:

35m

Step-by-step explanation:

The formula to find the volume of right circular cylinder is: V=πr^2*h

We know the following info:

V = 5390m^3

r = 7m

So the equation would be 5390 = 3.14*7^2*h

so h = 35m

Answer:

h ≈ 35.01m

Step-by-step explanation:

V=Лr²h

r =7m

v = 5390³

h= V / Лr²

h= 5390 / Л7²

=35.01409m

Alexander and Jo live 5 miles apart. They decide to leave their homes at 3 p.M. And travel toward each other. If Alexander bikes
lukranit [14]

Answer:

Step-by-step explanation:

Here is an illustration of the problem:

             ----------------------------->|<------------------

            A                                  t                     J

Alex and Jo start from their separate homes and drive towards one another.  The t indicates the time at which they meet, which is the same time for both.  Filling in a d = rt table:

              d           =        r        x        t

Alex                              14                t

Jo                                   6                t

The formula for motion is d = rt, so that means that Alex's distance is 14t and Jo's distance is 6t.

             

                      14t                               6t

   ---------------------------------->|<------------------

   A                                       t                      J

The distance between them is 5 miles, so that means that Alex's distance plus Jo's distance equals 5 miles.  In equation form:

14t + 6t = 5 and

20t = 5 so

t = .25 hours or 15 minutes.

If they leave their homes at 3 and they meet 15 minutes later, then they meet at 3:15.
