The surface area of a sphere:
A = 4 pi r^2
where pi = 3.1416
r is the radius
since diameter is given
r = d / 2
r = 16 / 2
r = 8
A = 4 pi (8^2)
A = 804 sq in is the surface area of the disco ball
Answer: i'm not really sure how to answer this one but i think you're wanting an answer to something. the equation for it would be 5 + 5x meaning the 5 is already there, and x is for the minutes that are they filling it up. so if the question asks how much after 5 minutes, you simply just put the 5 in place for the x.
The domain of the function is any positive real number and the range is any positive real number.
A + (-7) = -17
a + (-7) + 7 = -17 + 7
a = -10
