Question 1107913: The area of a circle is defined as A(r) = pr2. The surface area of a cylinder is defined as
B(r) = 2prh, where r is the radius of the cylinder and h is the height. Which function defines the total surface area of a cylinder with a height that is 3 less than twice its radius?
a. C(r)=2pr2 +2pr
c. C(r)=6pr2 –6pr
b. C(r)=4pr2 –4pr
d. C(r)=8pr2 +8pr

Total surface area = Curved surface area + Two
circular faces
= 2prh +2pr^2
But Height (h) = 2r-3
Total area = 2pr(2r-3)+2pr^2
4pr^2-6pr+2pr^2
6pr^2-6pr
