Volume of a sphere is 4/3 x pi x r(cubed)— so based on that I think it’s 2.14 cm cubed
The square root of 45 is simplified to 3 root 5. Rounded in decimal form, 6.708
Just do 6/3 because you have the area and one length, just divide the area by the height you have.

Answer: D) 144 square cm</h3>
========================================================
Explanation:
A square has all four sides that are the same length. So all four sides are 12 cm
area = side*side = 12*12 = 144 cm^2
Or you could say
area = (side)^2 = (12)^2 = 144 cm^2
Squaring a number is the same as multiplying it by itself. Hence the name "square" refers to a side length pairing up with its corresponding area value.

Side note: The perimeter is 4*(side) = 4*12 = 48 cm. It's possible that choice B is put in there as a trick answer.
