The Area of a circle is Pi (r)(r) so the area of a circle with the radius of 4, would be 16pi
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
The Area of a circle is Pi (r)(r) so the area of a circle with the radius of 4, would be 16pi
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 would be 50.3 square inches.
The area of a circle with a radius of 4 feet is: 50.27 square feet.
If you know the radius (say it's 4), square the radius and multiply that number by pi. So for a radius of four, it would be 4 X 4 = 16 X 3.14 = 50.24, the area of the circle.
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.
