Question

some fruits are sliced and packed into cylindrical cans of height 32 CM diameter of base 20 cm is placed around the curved surface of the can buy leaving a margin of to me from the top and bottom of the can find the surface area of the label​

Answer 1

Resposta:2009,6 cm or approximately 2 m

Explicação passo-a-passo:

First, to calculate de area of the label, I need to know the measure of the circumference of the base. To this, I'll use the following formula.

2xPIxR

I know that the radius measures the half of the diameter, that is...

20/2 = 10 cm <= that's my radius

2x3,14x10 = 62,8 cm

Now, I multiple the mesure of the circumference by the height, that because, I imagine that i opened the cilindrum, and the circumference will be the measure of the base.

62,8 x 32 = 2009,6 cm approximately 2 m
