Recall that a circle has a total of 360°, now the arc that is NOT part of "x", is 250°, therefore the leftover, namely the arc made where "x" is at, has to be 360° - 250<span>°, that's the degree measure of that arc.
now, arc's get their angle measure from the central angle they're in, in this case, "x" is the central angle, and therefore, it has the same measure of 360</span>° - 250°.
Answer: Total Surface Area
Step-by-step explanation:
Hi, to calculate the amount of cardboard needed to create a cereal box we have to calculate the total surface area.
The volume is used to calculate the amount of cereal that the box can contain, and the lateral surface area will not include all the cardboard needed for the complete box.
Feel free to ask for more if needed or if you did not understand something.
