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.
please mark me brainlies :)

Answer:
x = -70
Step-by-step explanation:
x+47=−23
Subtract 47 from both sides.
x+47−47=−23−47
x = −70
Cosθ is 3/5 because the cosine is found from the adjacent side of the triangle being divided by the hypotenuse. The sine is found by putting the opposite side from θ over the hypotenuse. If you draw this triangle out, the side across from θ would be 4 and the hypotenuse 5. In order to find the opposite side, you could either solve with the pythagorean theorem (a^2+b^2= c^2) or you could remember the properties of a triangle, therefore the final side is 3. You then put the opposite, 3, over the hypotenuse,5, in order to get 3/5 for the cosθ.
