Formula
for the circumference of a circle.
<h3>How did Archimedes find the circumference of a circle?</h3>
Archimedes stated in his Proposition that the area of a circle is equal to the area of a triangle with a base equal to the circumference and a height equal to the radius: (1/2)(r · 2πr) = πr2. Archimedes arrived at his approximation of the circumference of the circle by increasing the number of sides of the hexagon. Archimedes claimed that the area of any circle is equal to the area of a right triangle, where the radius of the circle is represented by one side and the circumference by the other.
Archimedes demonstrated using a similar method that the area of a circle of diameter D is equal to the area of a right-angled triangle with one side equal to the radius and the other to the circumference of the circle on the right angle.
Formula for the circumference of a circle:
A circle's area is equal to pi times the radius squared (A = r2). Discover how to apply this formula to determine a circle's area given its diameter.
The circumference is diameter x pi, or 2 x radius x pi.

Answer:
-8x-9y
Step-by-step explanation:
Hey There!
So basically this problem is asking you to simplify this expression using distributive property
The first step would be to distribute 7 into what is inside the parenthesis (2x and -3y)
2x*7=14x
-3y*7=-21y
so now we have 14x-21y + 4(3y-5x)
the next step would be to distribute 4 to what is inside the parenthesis (3y and -5x)
4*3y=12y
4*-5x=-20x
so now we have 12x-21y-20x+12y
the final step is to combine like terms
12x-20x=-8x
-21y+12y=-9y
so the simplified version of 7(2x - 3y) + 4(3y - 5x) is -8x-9y
If I'm rounding it, it'll be nine, but since you can't have a third of a person, I'd put ten.
