What is the perimeter of a square in centimeters circumscribing a circle of radius a centimeters?
The side of the square is equal to the diameter of the circle, in this case 2a so the perimeter is 8a cm.
What is the perimeter of a semi circle?
The perimeter of a full circle is 2*pi*r. Where, pi is the mathematical constant that is the ratio of any circle's circumference to its diameter, approximately equal to 3.14, and r is the radius of the circle. The perimeter of a semi circle, assumed to be half of a full circle is pi*r where pi and r are previously defined.
How do you work out the perimeter of a third of a circle?
The circumference of a circle is pi times the diameter. If you want a third of that, divide by 3. (Pi is approximately 3.14) Then to get the perimeter add the diameter to the circumference of the 1/3 of the circle.
How do you calculate half of a circle if the radius is 6 centimeters?
The answer depends on what characteristic of a half circle you want to calculate: its area or perimeter or something else.
What name is given to the perimeter of circle?
The perimeter of a circle is its circumference
What is the perimeter of a perfect circle?
The measure around a circle is called a circumference, rather than a perimeter. The term "perimeter" is used for polygons. The circumference of a circle is equal to the diameter, multiplied by pi - or to the radius, multiplied by 2 x pi. The number pi - which can be defined precisely as the ratio between the circumference and the diameter of a circle - is approximately 3.1416.
If A circle and rectangle have the same area the circle has a diameter of 42 centimeters and rectangle has a width of 18 centimeters find the perimeter of the rectangle?
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
What is the diameter of a circle with a circumference of 24 centimeters?
Since Pi is equal to the circumference over diameter, the diameter of a circle is equal to its circumference over Pi. So divide 24 centimeters by 3.14159 to get approximately 7.63943 centimeters.
Is the perimeter of a circle cubed?
No because the perimeter of a circle is its circumference
What is the name for the perimeter of a circle'?
circumference
What is the name of the perimeter of a circle?
The perimeter of a circle would be the circumference.
How do you find the area and perimeter of circle?
First you have to measure the diameter of the circle. The diameter is pi (pi is approximately 3.1415) times the diameter is the perimeter. Half the diameter is the radius and the area of a circle is pi times the radius squared. So for example, let us say that you have a circle with a diameter of 3 inches. The perimeter is then about 9.42 inches, and the area is about 7.07 square inches.
