To answer this question, you'll need to find the surface area of the top of the container (which is a circle), along with the surface area of the side of the container.Note that the diameter of the container is given and is 6 inches; therefore, the radius is ... what? Note that the height of the container is 8 inches.
he radius 3 inches.
you use that radius (3 inches) to calculate the area of the top of the container

L = 2πrh
Look up "area of a circle" or just "circle area." Still need to calculate the area of the top of the container.

L = 2πrh looks good. Mind defining L in words? Mind substituting r and h to calculate L?L means lateral surface are. i am not sure what you mean by substituting r and h


The answer 207
