Next, just divide both sides by 6.28, and your answer should be
Next, the diameter is just the radius times 2, which is 2.36.
Lastly, Area of a circle is . Using what we have, we can solve for area.
Firstly, solve the exponents:
Next, just multiply the right side, and your answer should be
In short, 1.18 cm is the radius, 2.36 cm is the diameter, and the area is 4.37 cm^2
