Explanation:
Here we want to find the largest area of a circle that can be made from a piece of thread 25.2 cm long, assume no knot .
This means that the circumference of the circle must equal to the length of the thread, so we can write:
L = 25.2 cm
And the circumference can be written as:
where
r is the radius of the circle
Solving for r, we find the radius:
The area of a circle is given by the formula
So in this case, we find:
