To figure this out the formula would be :
π(3.14)times radius squared.
Example:
What is the area of a circle with a radius of 4 cm?
Solution:
All you have to do is 3.14 times 4. Since the radius needs to be squared you would do 4 times 4 = 16. Then you multiply 16 with 3.14 and that would equal 50.24.
See it is very simple and I would know this because I like math. Just try it and it will be helpful!

Formula to find the area of circle?
Area of a circle = pi*radius2
Formula to find area of a circle?
The formula depends on the information available to you.
What is the radius and the area of a circle?
The radius of a circle is the distance from the center to any point on the circle. The area is the space within the circle. The formula to find the area is πr2. r stands for the radius of the circle. If you want to find the radius, you can work backwards from the area or the circumference, which is the perimeter of the circle. The formula for circumference is 2πr.
How do you find the radius of a circle when the area is given?
-- Take the formula for the area of the circle in terms of the radius . . . A = (pi) R2-- Solve that formula for 'R'. You'll then have a formula for the radius in terms of the area,which is exactly what you're looking for.
How do you find the diamter of a circle if you know the area?
In order to find the diameter of a circle if you have the area is to rearrange the formula for the area of a circle to put diameter as the unknown, like so: PIE*d = Area of a Circle d = (Area of a Circle) / PIE Therefore if the area of your circle is 40cm, 40/PIE = 12.73cm and that's the diameter.
What is the formula doe for the area of a circle?
The formula to find the area of a circle is: A = pi * r2
Formula to find area of circle?
The area of a circle can be found with the formula (pi)r^2
Formula to find the area of circle?
Area of a circle = pi*radius2
Investigate the formula of the area of a circle?
The formula to find the area of a circle is pi x the radius squared.
What is the formula to find area of circle?
The formula to find area is you do the radius squared times pi or 3.14
Formula to find area of a circle?
The formula depends on the information available to you.
How do you find the area of a circle in square inches?
By using the formula: area of circle = pi*radius2
What is the radius and the area of a circle?
The radius of a circle is the distance from the center to any point on the circle. The area is the space within the circle. The formula to find the area is πr2. r stands for the radius of the circle. If you want to find the radius, you can work backwards from the area or the circumference, which is the perimeter of the circle. The formula for circumference is 2πr.
Why does the formula to find area of a circle always work?
a formula is alway correct
If the area of a circle is 201.06 then the circumference of the circle is?
The formula to find the circumference of a circle is C = 2πr, where r is the radius of the circle. To find the circumference, you first need to find the radius by using the formula for the area of a circle (A = πr^2). Given that the area is 201.06, you can solve for the radius. Once you have the radius, you can plug it into the formula C = 2πr to find the circumference.
The formula used to find the area of a circle is?
Area = (pi) (R)2
How do you find the area of a circle in a square?
To find the area of a circle inscribed in a square, you can use the formula for the area of a circle (πr^2) and the properties of a square (all sides equal). Since the diameter of the circle is equal to a side of the square, you can find the radius of the circle by halving the side length of the square. Then, plug the radius value into the area of a circle formula to find the area.
