Area of circle = pi*212 = 1385.44236 square cm
Area of rectangle = 1385.44236 square cm
Lenght of rectangle = 1385.44236/18 = 76.96902 cm
Perimeter of rectangle = 2(76.96902)+2(18) = 189.93804 cm
The side of the square is equal to the diameter of the circle, in this case 2a so the perimeter is 8a cm.
The circumference of a circle with a diameter of 6 centimeters is 18.85 centimeters.
circle.
The perimeter or circumference of a circle = diameter times pi
The diameter of a circle with a circumference of 15 centimeters is about 4.775 cm
The circumference of the circle is larger than the perimeter of the rectangle.
The side of the square is equal to the diameter of the circle, in this case 2a so the perimeter is 8a cm.
add the perimeter of the rectangle, minus the side that'c covered by the semi circle. then, find the circumference of the semi circle [diameter x pi, divided by 2] and addd them together
The circumference of a circle with a diameter of 6 centimeters is 18.85 centimeters.
Pi (3.1415...) times the diameter of the circle = the perimeter
circle.
A circle with a diameter of 18 centimeters has an area of 254.47 square centimeters.
The area of a circle with a diameter of 8 centimeters is: 50.27 square centimeters.
Circumference (perimeter) of a circle = pi x diameter Diameter of a circle is the straight line distance from one side to the other which passes through the centre of the circle.
The perimeter or circumference of a circle = diameter times pi
Circumference ("perimeter") of a circle = (pi) x (diameter of the circle)
The perimeter of a full circle (circumference) is "pi" times the diameter. So the perimeter of a semi-circle will be half that; Perimeter = (pi/2) x (diameter).
