You use the formula:
area = pi x radius squared
If you approximate pi with 3.14, and replace the square with a product, that becomes:
area = 3.14 x radius x radius

How do you find area of a circle with pie?
The area of a circle is π (Pi) times the Radius squared.
What is the area of a circle if its circumference 12 pie?
The area of a circle if its circumference 12pi is: 113.1 units squared.
The diameter of a circle is 9 cm What is the area of the circle?
pie x 4.5 squared
What is the area of a circle when the radius is 180?
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 :)
A circular mat has a diameter of 20cm find its radius hence calculate the area of the mat use the value 3.14 for pie?
3.14*102 = 314 square centimeters
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.
How do you find area of a circle with pie?
The area of a circle is π (Pi) times the Radius squared.
Find the area of a circle with a radius of 8 meters to the nearest square meter Use 314 for?
There seems to be a typo in the problem you have...they are asking you to us 3.14 as pie or the symbol with 2 lines and a wavy line on top
How do you calculate the area of part of a circle?
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...
find the area of a circle with diameter 18m answers should be in pie form?
No
How do you get the radius of the circle with the circumference?
divide the circumference by pie (3.14) and the answer would be the radius. for example circumference = 314 pie = 3.14 so 314 divide by 3.14 = 100 so the radius = 100
How do you find a area a circle?
The answer depends on what information you are given.
What is pie r2?
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
How do you findArea of a circle?
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. :)
Find the area of circle?
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.
What is the area of the circle in terms of pie with a diameter of 36?
The area of a circle, in terms of pie, with a diameter of 36 is: about 324pi
If a circle has a circumference of 10 pie what is the circle's area?
This circle's area would be 78.54 units squared.
