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 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.
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.
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 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.
What is the name of the perimeter of a circle?
The perimeter of a circle would be the circumference.
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 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.
What is the circumference of a circle with a diameter of 12.5 centimeters?
The circumference of a circle can be calculated using the formula ( C = \pi \times d ), where ( d ) is the diameter. For a circle with a diameter of 12.5 centimeters, the circumference would be ( C = \pi \times 12.5 \approx 39.27 ) centimeters. Therefore, the circumference is approximately 39.27 centimeters.
