A = 50.265 square units.
the raidus of a circle is the distance from the middle of a circle to any point.
The relationship between the radius and area of a circle is as follows: Area of circle = 3.14 x Radius x Radius or 22/7 x Radius x Radius
64 pi ie just over 201 sq cm
if you have a radius in a circle do you use A=(3.14)d2
raidus means a scientific answer and is to be measured for something for example the earth it is 6400km raidus
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.
A 4-inch diameter circle has an area of 12.566 square inches.
The area of a circle with a radius of 4 units is: 50.27 square units.
The area of a circle with a diameter of 4 inches is: 12.57 square inches.
4 cm radius = Area of 50.26548 sq. cm.
The area of a 5-inch circle is: 19.6 square inches.The area of a 4-inch circle is: 12.6 square inches.The area of the 5-inch circle is 55.6% larger than the 4-inch circle
