Area = pi*22 = 12.566 square cm to 3 d.p.
4 cm radius = Area of 50.26548 sq. cm.
This indicates a radius of 4 cm, in which case the area of the circle is: 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.
A circle with a radius of 4 cm has an area of 50.27 square cm.
The area of a circle (in square hectometers) if the diameter is 4 cm is: 0.001257 hectometers2
The probability as a fraction that a point chosen at random within a circle of radius 10 cm will be inside a concentric circle of radius 4 cm is the ratio of the area of the smaller circle (4 cm radius) to the area of the larger circle (10 cm radius). Therefore, the probability is (4^2)/(10^2) = 16/100 = 4/25.
A circle with a radius of 6 cm has an area that is about 113.1 cm. 3/4 of that is 84.825 cm
The area is about: 50.27 square centimeters.
A=Pi(r)2 - A circle with a radius of 4 cm has an area of 50.27 square cm
12.57 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
