The area of a circle is pi times r squared.
The base of a cylinder is a circle. So we can use the area formula for a circle. Area = πr2 where r is the radius of the circle, and pi is the ratio of the circumference of the circle to its diameter.
circumference divided by pie divided by two
A circle.
Here is the formula for area (you do the math) pi = 3.14 r = radius Area = pi * r2
the definition of rule in math is what step you need to answer a question. what should you do to answer a problem.....you have to follow the rule to able to answer a problem..for example :-to find the area of a circle. you have to follow the formula of the circle . which is A= radius square pi. if u follow the rule your answer will be correct.....
radius times two
the formula is: circumference= p*diameter
That's the formula for the area of a circle.
You don't... I am a math teacher... you need to use the formula!

The length of one arch of a cycloid generated by a circle of radius r is 8r.

The formula is:Volume of a circle = 0
Area formula for circle= --,,- r 2
