Question 302791
The juice can can be modelled as a cylinder.

Surface area of a cylinder is {{{ 2*pi*r*h + 2*pi*r^2}}}
where r = radius and h = height of the cylinder

h=18 cm 
r = diameter ÷ 2 
r = 5/2 cm 
r = 2.5 cm 

Surface area of the juice can = {{{ 2*pi*r*h + 2*pi*r^2}}}
= {{{2*pi*2.5*18 + 2*pi*2.5^2}}} cm^2
= 332 cm^2
