Area of a circle is pi times radius squared.
Diameter is basically radius times 2  
16 divided by 2 is 8
So you do pi times 8 squared
8 squared is 64
You do pi times 64
or 3.14 times 64
the area is 200.96

In ancient egypt, a scribe equated the area of a circle with a diameter of 9 units to the area of a square with a side length of
Rudik [331]

Answer:

\pi =3.160494

Step-by-step explanation:

step 1

Find the area of the circle with a diameter of 9 units

we know that

The area of a circle is equal to

A=\pi r^{2}

we have

r=9/2=4.5\ units ----> the radius is half the diameter

substitute

A=\pi (4.5)^{2}

A=20.25\pi\ units^2

step 2

Find the area of a square with a side length of 8 units

we know that

The area of the square is

A=b^2

where

b is the length side of the square

we have

b=8\ units

substitute

A=(8)^2=64\ units^2

step 3

Equate the areas

20.25\pi=64

solve for \pi

\pi =\frac{64}{20.25}=3.160494
