I Really Need Help With This Question!!

What is the area of the label on the side of a soup can if the radius of the can is 2 inches, the height is 4 inches, & the label completely covers the sides?

Answers:
a.) 16 & pie symbol square inches
b.) 16 square inches
c.) 4 7 pie symbol square inches
d.) 8 square inches

so the width of the label is the circumference of the can

C = 2π(2) = 4π
so area = 4π(4) = 16π
