Option C is correct
Answer:
Surface Area = 283
Step-by-step explanation:
Radius = 3
Height = 12
Formula for suface area is SA= 2πrh+2πr^2
let "r" be for radius
let "h" be for height
SA=2*π*3*12+2*π*3^2
SA=282.74
round to the nearest ones spot and that will make the surface area = 283
Yea what she said was correct
