The ball is a sphere.
Volume of a sphere =
where pi = 3.14 and r = 3.5 cm, (which is half the diameter)
Substituting them in, gives us the answer.

Answer:
The area is 78 square inches
Step-by-step explanation:
so you can split the hexagon into two trapezoids, and then find the area of one of those trapezoids, which is what I did. The area of a trapezoid I think is
a, b=base, h=height
A=a+b/2*h
is a really bad way of saying it, but that's how I know to do it.
So anyways I just substituted the numbers with their corresponding letters and solved. So the area of one trapezoid was 39, and since we have two 39's, you do 39*2 and you get 78.
Hope I helped
Answer:
64
Step-by-step explanation:
The volume of a prism is defined by the product of its length (L) times its width (W) times its Height (H):
So, if these dimensions are increased each by a factor of 4, the volume now becomes:
That is 64 times the original volume LWH
