Which circle is bigger: One with an area of 30 square units or one with a circumference of 30 units? How do you know?

growing circle

Therefore, a growing circle would reach an area of 30 square units before reaching a circumference of 30 units, so the circle with a circumference of 30 units would be bigger.

step-by-step explanation:

rectangles are made up of 4 right angles, which means that a side and a base meet perpendicular to one another.   their slopes then have to reflect perpendicular slopes.   perpendicular slopes are opposite reciprocals of one another.   for example, if the slope of one line is +2/3, then the perpendicular slope to that would be -3/2.   so we look for that combination in our choices.

all of them satisfy that condition (so what's the question, i guess? )

wait this depends wether emily and zach how they are thinking.

yes they are the same.
