In order to find the area of the circle, you must know the formula:
TTr2
You must square the radius before multiplying by pi. (If you are presented with the diameter, not the radius, divide by two) Next, multiply the squared radius by pi.
Example:
The diameter is 4 inches.
Nothing - if you double the radius you will get the diameter. The area of the circle will remain the same
Area of a circle = pi*radius2
Find the area of the circle and divide by 4.
how do you find the area of a semi circle
A semicircle is 1/2 of a circle. Find the area with the diameter you are given as if you had a whole circle, then divide that answer by 2 to get the area of the semicircle.
If yo have the area of the circle, the square is irrelevant. Radius = sqrt(Area/pi)
Nothing - if you double the radius you will get the diameter. The area of the circle will remain the same
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
To find the area of the circle pi*radius*squared and subtract the area of the figure inside
Area of a circle = pi*radius2
Find the area of the circle and divide by 4.
First find the area of the larger circle and then subtract the area of the smaller circle. Area=(pi x radiuslarger)-( pi x radiussmaller)
Circumference of any circle = 2*radius*pi or diameter*pi
area of a circle = pi*r2
Area of a circle = pi*radius2
To find the diameter you need to know what the radius of the circle which is from the center to the circumference ,the edge, then you times it by two and that's how yo find the diameter
