Question

Find the surface area of a cylinder with d = 12 in: h = 14 in

Answer 1

base is a cricle, area of circle is pi*r^2

Answer 2

radius is d/2 = 6
base = pi*6^2 in

Answer 3

sorry, you have to add the basse to the 'lateral' area

Answer 4

so it's 2*base + circunference*height

Answer 5

circunference is pi*d
C=pi*12in

SA = 2(pi*6^2)+(pi*12) = 84pi

Answer 6

113.04 sq. in.
B.
640.56 sq. in.
C.
527.52 sq. in.
D.
753.6 sq. in. these are my choices
