D again because as you can see....it does not touch the x axis at all, but the y axis is at -8
The formula for the surface area is given and as follows.
SA = (2)(3.14)(r^2) + (2)(3.14)(r)(h)
The radius of the cylinder is 4 inches and the height is 9 inches. Using the given values, we can plug them into the formula and solve for the surface area from there.
SA = (2)(3.14)(4^2) + (2)(3.14)(4)(9)
SA = (6.28)(16) + (6.28)(36)
SA = 100.48 + 226.08
SA = 326.56 in^2
Hope this helps!! :)
Answer:
3.72
(its not rounded I just calculated it and got that, hope it helps:)
