Answer:

Step-by-step explanation:

ABC has a perimeter of 23, so

AB + BC + AC = 23

The perimeter of ABE would be the sum of these sides:

AB + BC + CD + DE + AE

We also know:

AE = AC, CD=4 and DE=4 because ACD is congruent to AED

So, AB + BC + CD + DE + AE = AB + BC + 4 + 4+ AC = 23+8 = 31

If you draw a net for a cylinder, such as a soup can, how many two-dimensional geometric shapes would this net have?

Nezavi [6.7K]

Answer:

If you were to “unroll” a can of soup, you would end up with two circles and one rectangle.

Thats why when you are finding the surface area of a cylinder, you need to multiply the area of the circle by 2. And also you need to find the area of the rectangle. Then you add the areas all up.
