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.
- Divide the diameter by 2. (Which gives you 4)
- Square the radius. (4 x 4 is 16)
- Now, multiply the squared radius by pi.
- This gives you 50.265. (Rounded)

What happens to the area of a circle if yo double the radius?
Nothing - if you double the radius you will get the diameter. The area of the circle will remain the same
How do you find the area of a circle if the circle is 8cm?
Area of a circle = pi*radius2
How do you find the area of only .25 a circle?
Find the area of the circle and divide by 4.
How do you find the area of 16 wide and 27 long that has a semi circle?
how do you find the area of a semi circle
How do you find the area of circle when its half of the circle?
Find the area of the whole circle and divide by two. Area of semicircle = 0.5*pi*r2, where pi = 3.14159 and r is the radius
How do you find the radius of an inscribed circle of a square given the area of the circle?
If yo have the area of the circle, the square is irrelevant. Radius = sqrt(Area/pi)
What happens to the area of a circle if yo double the radius?
Nothing - if you double the radius you will get the diameter. The area of the circle will remain the same
How do you find the area of a circle inside a square?
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
How find the area of a square when a circle is inside?
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
How do you find the area of a shaded circle and the area of an unshaded circle on that is inside the other circle?
To find the area of the circle pi*radius*squared and subtract the area of the figure inside
How do you find the area of a circle if the circle is 8cm?
Area of a circle = pi*radius2
How do you find the area of only .25 a circle?
Find the area of the circle and divide by 4.
How do you find area of a circle with another circle in it?
First find the area of the larger circle and then subtract the area of the smaller circle. Area=(pi x radiuslarger)-( pi x radiussmaller)
How yo find circumference of circle?
Circumference of any circle = 2*radius*pi or diameter*pi
Formula to find the area of circle?
Area of a circle = pi*radius2
How do you directly find the area of a circle?
area of a circle = pi*r2
How do you find diameter of circle?
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
