Question

A can of sweet peas at the local grocery store has a radius of one inch and a height of two inches. How much paper is used for the label on the can of peas?

Answer 1

lateral surface area of cylinder  is  2πR *h
R radius =1 inch,
h height =2 inch
2*π*1 *2=4π=12.57 inch²

Answer 2

Answer:

12.56 inch²

Step-by-step explanation:

r = Radius of can = 1 inch

h = Height of can = 2 inch

Paper required will be equal to the lateral surface area of the can. Lateral surface ignores the area of the top and bottom of the can. We will use lateral surface area as cans are only labelled on the sides and not the top and bottom.

Lateral surface area of the can

2πrh

= 2π×1×2

= 4π

= 12.566 inch²

Paper used for the label on the can of peas is 12.566 inch²
