To find the area of the circle pi*radius*squared and subtract the area of the figure inside
The circumference of a circle is the distance arround the edge of the circle. The area of a circle is how big the inside of the circle is.
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.
Since area of a circle = πr^2, a circle with r=1 would have an area of π.
Area of a circle = pi*radius2
An entire circle is 360 degrees. 90 deg is 1/4 of that. Area of a circle is A = pi r^2 area of this sector is (1/4) pi r^2 = (1/4) x 3.14 x 4x4 =12.56
its when you leave the answer with ╥ in it e.g. if they go find the area of a circle (Pi.r.r or squared) you find the radius say 4cm then you put in in the formula so piX4X4 so you then find out 4X4 which is 16 so the area of a circle with a radius of 4cm in terms of ╥ is 16╥
Area of a circle = pi*radius2
Area of a circle = Pi * radius2
Area of a circle = pi*radius2
Area of a circle is calculated by A=2*p*r where A represents the circle's area and r is the radius of the circle.
The area of a circle is the amount of space inside the circle. The area of a circle is calculated by multiplying pi(3.14159) by the radius squared.
Using 3.14 as Pi the area of circle is: 0
the area of the circle is increased by 400%
Area of a sector of a circle.
Area of any circle = pi*radius2
The circle's area is 70,900,000 square units.
