Area of any circle = pi*radius squared
Area of a circle = pi*radius2
Area of circle = 78.54 sq cm => Radius of circle = 5 cm => Diameter of circle = 10 cm => Side of square = 10cm => Area of square = 100cm2
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.
Area of the circle in square cm = pi*radius2
314.29 cm
The area of a circle whose diameter is 10 cm is: 78.54 cm2
Area of a circle = pi*radius2
A circle with a radius of 10 cm has an area of 314.16 square cm
Area of circle = 78.54 sq cm => Radius of circle = 5 cm => Diameter of circle = 10 cm => Side of square = 10cm => Area of square = 100cm2
Area of a circle = pi*radius2
Area = 78.54 cm2Circumference = 31.42 cm
The area of a circle with a radius of 10 cm would be 100 times pi, or, rounded to the nearest hundreth, 314.15 cm2.
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.
