The equation for circumference is:
The equation for area is:
First, we'll find the circumference.
The 'r' in the equation stands for radius. The radius of a circle is half of its diameter, so the circle's radius is half of 6--3 inches.
So, we can substitute 3 in for 'r' and 3.14 in for
Then, we can simply multiply.
Therefore, the circumference of the circle is 18.84
Next, we'll find the circle's area.
Again, we can substitute 3 in for 'r' and 3.14 in for
The, we'll square three and multiply.
Therefore, the circumference is 18.84 and the area is 28.26.
