4 cm radius = Area of 50.26548 sq. cm.
Area of a circle = pi x (radius)2So, if the radius is 4 cm, the area is pi x 42= 50.265 cm2
The area of the circle will be 4 times greater
the area of the circle will be 1/4 of its original area
Since you said radius, I assume you mean Circle or Sphere. Circle: Area = Pi * radius^2 therefore, Radius = Square Root of (Area/Pi). Sphere: Area = 4/3 Pi * Radius^3 therefore, Radius = CubeRoot of (3/4 * Area/Pi)
The area of a circle with a radius of 4 is: 50.27 square units.
The radius of the circle is 2 units. * * * * * If the area is 4 units, the radius is 1.128 units
The area of a circle with a radius of 4 units is: 50.27 square units.
4 cm radius = Area of 50.26548 sq. cm.
The area of a circle with a radius of 4 feet is: 50.27 square feet.
A circle has only one measure for its radius. A shape that has a "radius" of 3 in by 4 in cannot be a circle.
The area of a circle is pi times the square of the radius: A = πr2. For a circle of radius 4, this is π x 42 = π x 16 = 50.265 units squared.A circle with a radius of 4 units has an area of 50.27 square units.
A circle with a radius of 4 cm has an area of 50.27 square cm.
A circle with a radius of 4 cm has an area of 50.27 square cm.
A circle with a radius of 4 cm has an area of 50.27 square cm.
Area of a circle = pi x (radius)2So, if the radius is 4 cm, the area is pi x 42= 50.265 cm2
