Volume of a ball = 4/3 x PI x r^3
r = half the diameter.
Volume of 1 ball = 4/3 x PI x 2^3 = 33.5 cubic inches.
Multiply the volume of 1 ball by total balls:
33.5 x 4 = 134 cubic inches.
Answer:
10 +2x
Step-by-step explanation:
Put the given values into the perimeter formula and simplify.
P = 2(L+W)
P = 2(5 + x)
P = 10 +2x . . . . the perimeter of the rectangle in units
21.625 is your answer to 865/40
Check the picture below.
recall that a reference angle, is the angle made with the x-axis, regardless of the Quadrant the terminal point is at.
what's its tangent? well, you can check your Unit Circle, if you don't have one, you'd want to get one about now, you can search online for one, quite a few to get there, anyhow, at that point, the "x" and the "y" are the same value, and thus the tangent is 1.
The answer is C.
You have to subtract 13 from both sides.
