Circumference = Pi * 2 * Radius
27 feet = Pi * 2 * Radius
13.5 feet = Pi * Radius
(13.5 / Pi) feet = Radius
So around
4.77464829 feetCircumference = 2 x radius x pi [diameter = 2 x radius] So: Circumference = diameter x pi Diameter = Circumference / pi Diameter = 27/3.1416 Diameter = 8.60 cm
Circumference = 27 cm So radius, r = 27/Pi = 4.297183 cm Then surface area = 4*Pi*r2 = 232.05 cm2
To calculate the area/circumference of a circle when designing something circular with a limited amount of material. i.e. you have to design a bronze circle and only have 27 sq ft of bronze. You have to calculate the circumference to see if you need to make the circle smaller or not.
The "27" can be either the radius or the diameter. The main number that is needed is Pi. Pi is equal to 3.141592654....... Therefore, the formula is as follows: C=2(Pi)(r) or C=Pi(d).C=2(Pi)(27) --> C=169.6460033...=169.65C=Pi(27) --> C=84.82300165...=84.82The answer can either be 169.65 or 84.82 depending on the situation.
It is: 3.14*272 = 2289.06 square cm
The radius is 4.3 feet.
The radius of the circle is 4.296739857 and its circumference is 27 feet rounded
Circumference of circle: 2*pi*27 = 169.65 feet rounded to two decimal places
Circumference = 2*pi*r = 169.6 feet.
Circumference of a circle is given by 2πr. Circumference(c) = 2πr = (2r)π = dπ [ r is radius and 2r = d (diameter) ] So circumference of a circle is also given by dπ. We have, c = 27 feet So, dπ = 27 feet d = (27/π) feet = 8.594 feet So the diameter of the circle = 8.594 feet.
The circumference of a circle whose diameter is 27 feet is about 84.82 feet.
Circumference of a circle = 2*pi*radius or pi*diameter
The circumference of a circle if the radius is 27 inches is: about 169.6 inches. (you can do this type of calculation for other circles using this formula: r x 2 x Pi = circumference).
The circumference of a 27-foot diameter circle is about 84.82 feet. (diameter x Pi = circumference).
Approx 4.3 inches.
pi*27 feet
Circumference of circle: 2*pi*4.3 = 27 units rounded
