The formula for the area (A) of a circle is A = πr2.
If the area is 100π then 100π = πr2 : 100 = r2 : r = √100 = 10.
The radius is of length 10 units.
3850m is the area of the a circle whose radius of 7meaters
what about such a line segment? the length of such a segment is called the radius. the area of the circle is pi*the length of this segment squared the circumference is 2*pi*the length of this segment
Area = pi*r2Area = pi(5.29 cm)2= 87.9 cm2=========
A circle of radius, r, has area pi r2. The largest square inside it is made up of four isosceles triangles whose equal sides are of length, r, and thus has area 1/2 r2. Thus the area of the contained square is 2 r2.
The area of a circle, if the radius is 5 cm, is: 78.54 cm2
10 units of measurement
The area of a circle is equal to that of a triangle whose base has the length of the circle's circumference (distance around the circle) and whose height equals the circle's radius which comes to Pi multiplied by the radius squared. Area of Triangle 1/2 *base*height
Radius is x2 so area is x4.
The area of a circle whose radius is 19 centimeters is: 1,134 cm2
3850m is the area of the a circle whose radius of 7meaters
The radius of a circle whose area is 3.14 square centimeters is: 1 cm
A circle with a radius of 7.75 meters has an area of 188.69 square meters.
A circle with a radius of 6.6 inches has an area of 136.85 square inches.
The area is 314 cm2
A circle with a radius of 6 units has an area of 113.1 square units.
A circle with a radius of 21 cm has an area of ~1,385.44 square cm
the area of the circle will be 1/4 of its original area
