divide the square feet by pi that gives you the radius squared find the square root and get the radius
Radius of circle is the square root of 154/pi = 7 units rounded
Since the area of a circle is (Pi)times(Radius squared) then you would reverse the process to find the radius, and hence, the diameter. Divide the area by Pi (3.14159...) and you would have the radius squared. Take the square root of that and you have the radius. To get the diameter, multiply the radius by 2.
The area of a circle equals pi times the radius squared (A = pi*radius2) where pi is 3.1416 So the radius is the square root of the area divided by 3.1416
First we have to find the radius: 2*pi*radius = 18*pi Divide both sides by 2*pi to find the radius: radius = 9 inches Area of a circle = pi*radius2 Area = pi*92 = 81pi or 254.4690049 square inches
Area of a circle in square meters = pi times radius squared
A=Pi(r)2 - A circle with a radius of 24 meters has an area of 1809.56 square meters.
Half the square root of the square radius equals the circle radius.
If A = 37 m2 then r = 3.43 m
If the radius is 42 meters, then you already know the radius.
The area of a circle is pi multiplied by radius squared. Thus, if the radius is 2.35m, the area is 17.3 square meters.
The same as half the side of the square, as the radius of the circle is half its diameter, and the diameter of the circle is equal to the side of the square.
Use the equation: Area of Circle = pi * r^2 so... 100 pi = pi * r^2 The pi's cancel out. 100 = r^2 Square both sides to find the radius. square root(100) = r, the radius of the circle
If yo have the area of the circle, the square is irrelevant. Radius = sqrt(Area/pi)
The circumference of a circle is 15\piπ m. Find its radius, in meters. The Answer Should Be 7.5
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.
First we have to find the radius: pi*radius2 = 400*pi square meters Divide both sides by pi and then square root both sides: radius = 20 meters 2*pi*radius or pi*diameter = circumference 2*pi*20 = 40*pi meters
