A tube of tennis balls has the following measures: a 4 diameter of 4 inches and a height of 8 inches. What is the surface area of the tube of tennis balls?

40 or 125.66

Step-by-step explanation:

Use the formula 2r² + 2rh

2(2)² + 2(2)(8)

8 + 32

= 40 or 125.66

step-by-step explanation:

through just a quick inspection, one can see that the graph of this cubing function starts in quadrant iii and ends in quadrant i.   when x = 0, y = 3, so the y-intercept is (0, 3).

if graphs are part of the problem statement, share them.   .
