What is the largest area of a circle that can be made from a piece of thread 25.2cm long assume no knot

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:

indicate valleys, hills, steepness and gentleness of slopes.

explanation:

contour lines on a map indicate elevation, or depth. numeric notations on contour lines refer to the level of elevation, or height about sea level.

the dependant variable is spilled water

the independent is the heat
