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:
B. Quadratic, degree 2
Step-by-step explanation:
ALl you have to see is the degree. The degree is the largest exponent of the expression. The largest exponent here is 2 and since there is only one answer with a degree of two, the answer is b.
Answer:
Step-by-step explanation:
Your answer cannot be MORE precise than the least precise measurement. For addition and subtraction, look at the places to the decimal point. Add or subtract in the normal fashion, then round the answer to the LEAST number of places to the decimal point of any number in the problem.
The expression is equal to one. Because a number over the same number is equal to one. I think that is the answer.
Hope this helps!
