Answer:
3,136cm^2
Step-by-step explanation:
A square has 4 sides that are all equal to each other. This means the perimeter can be divided by the number of sides to find the measurement of each side.
224cm ÷ 4 = 56cm
Each side is 56cm
To find the area, we must multiply base and height. Since it is a square, it will be 56cm × 56cm.
56cm × 56cm = 3,136cm^2

Using the volume formula, we will see that the volume of the sphere is V = 381.51 cm^3

How to get the volume of the sphere?</h3>
For a sphere of radius R, the volume is given by the formula:

In this case, we can see that the diameter is 9 cm, then the radius is half of that:
R = 9cm/2 = 4.5cm
Now that we know the radius, we can replace it on the volume formula to get:

Answer:
PR = 8
Step-by-step explanation:
The median bisects the side opposite the vertex, so ...
P is the midpoint of AC
Since AC = 25, the length of half that segment is PC = 12.5. Of course, that is the sum of segments PR and RC:
PR + RC + PC
PR + 4.5 = 12.5 . . . . . fill in the known values
