Answer:
Base: 8cm. Height: 21cm
Step-by-step explanation:
We know that the base of a rectangle is 13 cm. longer than the height and the perimeter is 58 cm. Here is how we would set up the problem:
2x+2(x+13)= 2x + 2x + 26 = 4x + 26 = 58 (now we use the distributive property:
4x + 26 = 58
        -26   -26
4x = 32
So, the base is 8 cm. 
Now it's time to find the height.
So, we know the base (in total) is 16 cm. Now we do 58-16=42. Now we divide 42 divided by 2 = 21 cm.

Answer:
V = 4/3 pi r^3  for a sphere
Step-by-step explanation:
You can't a circle is a two dimensional object.
The volume of a sphere, which is the three dimensional form of a circle is found by
V = 4/3 pi r^3
Where r is the radius
