Use the net to find the surface area of the cylinder. give answer in terms of pi.

THIRD OPTION

Step-by-step explanation:

To solve the exercise you must add the area of the circles (which are equal) and the area of the rectangle.

(Multiply the formula of the area of a cylinder by 2, because both are equal)

The area of a circle is:

Where r is the radius

The area of a rectangle is:

Where l is the lenght and w is the width.

The lenght of the rectagle is the circumference of the circle:

yd

Then the area of the cylinder is:

56yd²

Step-by-step explanation:

A=2

=2× × 2yd ×12yd +2××2yd×2yd

=48 yd² + 8yd²

=56 yd²

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.
