The area of a circle if its circumference 12pi is: 113.1 units squared.
pie x 4.5 squared
well the diameter will be 90 and the radius is obviously 180, so you will need to take pie radius squared to find the area, simply press the pie button on your calculator then 180 and then the square button :)
all you do is find the area of the circle... if you mean find the squares area, find the area of the circle, and then the square's area and subtract the squares area to the circles area
You find the area of the whole square first. Then you find the area of the circle inside of it And then subtract the area of the circle from the area of the square and then you get the shaded area of the square
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.
To work out the area of a circle, you have to learn something called 'PIE'or 'PI' in Greek. Pie = 3.14. Search 'What is pie?' on this to find out the next part...
No
The answer depends on what information you are given.
Pie r2 is the formula needed to find out the area of a circle you have to square the radius of the circle (half the diameter of the circle) two times (btw square means times the number by it self) and times the answer by pie which is 3.14
well the formula to find the area of a circle is Area=pie x radius squared so if i say calculate the area of a circle with the following measurements giving your answer in terms of pie. Radius=8cm Area=pie x radius squared Area=pie x 8 squared Area= 64 pie cm squared If you do this calculation on your calculator ( pie x 8 squared) you should get the same answer. I hope this helped. If you need anything else veryfying then please ask. :)
The area of a circle, in terms of pie, with a diameter of 36 is: about 324pi
Area of circle can be computed using formula is A = πr2 , where, A = represented is Area of circle, π = its constant, call it as pie and value is 22/7 i.e 3.142, r = Radius of circle, which has to be squared or doubled to get area of circle.
This circle's area would be 78.54 units squared.
Find the radius of the circle (if it gives you the diameter just half it to get the radius) and then square it. Then times your answer by pie. So the formula is: A= pie (r squared) P.S. Sorry I couldn't get the mathematical symbols!
Main Answer: To find out the area of the circle you must square the radius. Here's the answer: I took pie as 3.141592 Area = pie x radius squared A = pie x 13.25 squared --> pie x (13.25 x 13.25) A = 551.5457455 Don't forget to put the units on (e.g. mm, cm, etc) and round to whatever number of decimal places this question asks for. Extra Info: Circumference of a circle = pie x diameter Area of a circle = pie x radius squared C herry pie's d elicious --> C = pie x d A pple pie's r 2 --> A = pie x r2
