Area of circle in square inches = pi*radius squared
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.
If the radius is 4, the width is 8 inches. If it is a 4 inch circle diametrically the width is 4 inches
Area of a circle = pi x (radius)2So, if the radius is 4 cm, the area is pi x 42= 50.265 cm2
Area of circle: pi times 2 squared = 4*pi square inches
Area of circle in square inches = pi*radius squared
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
Calculate the radius, which is simply 1/2 the diameter. Then use the standard formula for the area of a circle. ________________________________________________________________ The circle area = (pi) x diameter / 4 = 3.14 x 25/4 = 19.625 Sq inch
The area of a circle with a radius of 4 units is: 50.27 square units.
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.
If the radius is 4, the width is 8 inches. If it is a 4 inch circle diametrically the width is 4 inches
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.
