How do you find the radius of a circle if you only know the area?
Radius = +sqrt(Area/pi)
Describe the effect on the area of a circle when the radius is doubled?
the radius is from the center of the circle to the edge so that's how you find the radius.
Find the radius of a circle of with area of 400?
11.3
How do find the area of a circle?
Pi x radius(R) squared e.g radius of circle is 5cm A=3.14x5 squared Area is 78.5
The area of a circle is 154 square meters Find the radius?
The radius is 7 meters.
How do you find ratio of area to radius?
In a circle, the area of the circle is pi times the radius squared
What is the radius and the area of a circle?
The radius of a circle is the distance from the center to any point on the circle. The area is the space within the circle. The formula to find the area is πr2. r stands for the radius of the circle. If you want to find the radius, you can work backwards from the area or the circumference, which is the perimeter of the circle. The formula for circumference is 2πr.
How do you find the radius of circle with area 144pi?
Equation for the area circle = pi x radius squared If the area is 144pi, then you need to find the square root of 144, which is 12. Therefore, radius = 12
Why do you find the area of a circle with pi times the radius squared?
You find the area of a circle with pi times radius squared because the radius is half the circle so to find the full area you need to multiply it again.
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)
How to find area of a circle?
you take the radius and multiply it by itself. then you multiply the radius squared by 3.14 to get the area of a circle...
How do you find the radius and diameter of the circle if you know the area?
Area of Circle = pi (radius)2 So , using this formula we can find the radius and also the diameter. Diameter = 2(radius)
How do you find a area a circle?
The answer depends on what information you are given.
When you know the radius of a circle how can you find the area?
Area of a circle = pi*radius2
How do you find the area of a circle by only knowing the radius?
Since the area of a circle is pi times radius squared, take the radius and square it. Then, multiply that by 3.14, or pi to get the area of the circle.
What is the circumference and area of a circle that has a radius of 4?
To find the circumference of a circle then multiply pi (3.14159265...) by the diameter of the circle. To find the area then multiply pi by the radius squared.
What is the required piece of information tho find the area of a circle?
The only piece of information required to find the area of a circle is the radius of the circle. Once you know the radius of the circle, the area is simply the radius squared multiplied by pi (approximately 3.14).
