hi there!

the answer will be d: 2

13.46

step-by-step explanation:

16.80 x .20 = 13.46

for this case we have that by definition, the surface area of a cylinder is given by:

where:

r: it is the radius of the cylinder

h: it is the height of the cylinder

we can also rewrite it as:

where:

la: it's the lateral area

ba: area of the base

option a

divide the numbers
