Half the square root of the square radius equals the circle radius.
Find the distance of the point from the centre of the circle. If the distance is - less than that radius then the point is inside the circle, - equal to the radius then the point is on the circle, and - greater than that radius then the point is outside the circle.
If yo have the area of the circle, the square is irrelevant. Radius = sqrt(Area/pi)
use the equation Area=pi*r2 r is the radius of a circle If you are presented with the diameter of the circle, divide by 2 to receive the radius. Now, square and multiply by pi.
A square does not have a radius. A square, with sides of length x units, can have an inscribed circle. Such a circle would have a radius of x/2 units. Or the square could have a circumscribing circle. This would have a radius of x/sqrt(2) units.
Area of any circle = pi times radius squared.
You measure the radius of the circle and then square it and multiply by Pi.
divide the square feet by pi that gives you the radius squared find the square root and get the radius
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
The radius is 7 meters.
the circumfrence of a circle is pi times it's radius squared.
It depends on the values you have. The base of a cylinder is a circle. If you know the circle's diameter, half it to find the radius. If you know the circle's circumference, divide by 2pi to find the radius. If you know the circle's area, divide by pi and take the square root to find the radius.
Area of a circle in square meters = pi times radius squared
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
To find the area of the circle pi*radius*squared and subtract the area of the figure inside
Radius is the square root of (area divided by pi).
To find the area of a circle for fifth grade, what one has to do is to first find the radius, the radius is the distance from the central point to all points on the circle, once the radius is found, square the radius. Then multiply the squared radius by pi.
Circumference is the length around the circle C = 2 pi (r) r is radius half of diameter Area of a circle is the number of square units inside the circle A = pi (r)^2 r is the radius again
Radius of circle is the square root of 154/pi = 7 units rounded
Find the radiusMultiply pi by the square of the radius.
A circle with radius 15mm will fit in a 30mm square. Find the intersection of the square's diagonals, that is the center of the circle.
Area of a circle = pi*radius2 The radius of the circle will be 1/2 the size of the length of a side of the square.
Divide the area by pi then square root your answer which will give the radius of the circle and use 2*pi*radius to find the circumference.
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.
Divide the area by pi and then square root it this will give the radius of the circle.
