Circumference of circle: 31*pi = 97.389 inches rounded to 3 decimal places
The circumference of a circle with a 31 foot diameter is 97.4 feet, approx.
31 inches
That will depend on the circumference of the circle which has not been given
.31 inches to the right
If you are considering a circle, where the central angle is 124o of 360, then, we have the diameter, 2r, multiplied by pi, and then a twist, multiplied by the ratio of the angle (ABC in this case) and 360 (the total measure of the circle). Therefore, we have:2pi(r) * (124/360) = 2pi(r)*(31/90) = 31/45 pi * r.However, with the information you provided, we are unable to deduce a complete numerical answer for arc AC.However, considering you meant that the point B is located on the circumference of the circle, then that is a different matter.We now have a circle, with the diameter shown, and chord BC is given, we can draw a line from the center of the circle where the diameter is, and connects with point C. Thus, we have another radius section (DC, given D is the center). Then, we have the radius stretching from point D to B. Thus, we have an isosceles triangle. This means that angle C = angle B. Now, because there is 180 degrees in a triangle, and angle C = angle B, we have:180 - 2a = a2Now, a line is also 180 degrees so subtracting 180 degrees, we have:180 - (180 - 2a) = Angle D180 - 180 + 2a = Angle D2a = Angle DNow, we know that a is the angle, thus, subsituting in the equation, we have 2(124) = 248o.Using the above information, we could multiply by 2 (248 is twice of 124), thus giving 62/45 * pi* r. (2pi*r * 248/360 = 2pi * r * 31/45 = pi * r * 62/45)
31x3.1416=circumference
Circumference = Diameter*pi So diameter = Circumference/pi = 32*pi/31 = 32
The circumference of a circle with a 31 foot diameter is 97.4 feet, approx.
31 feet 5 inches
if the circumference is 31 inches you know that... Diameter = circumference/(pi) D = 31in/3.1 D=10 r= 1/2D r=1/2(10) r=5
31 feet 5 inches
The circumference of a circle with a radius of 31 meters is about 194.8 meters.
Circumference = 2 * Pi * rr(radius) = diameter/2 = 31/2 = 15.5Circumference = 2 * pi * 15.5= 97.4 units==========( you could call it 97 units )
Improved Answer:-Its radius: circumference/diameter = piIts area: pi*pi squared = 31 square cm rounded to nearest integer
Circumference will be 120 pi inches, ie 31 feet and very nearly 5 inches
The first 31 digits of Pi, a greek letter that represents the numerical relationship between a circle's diameter and circumference, amongst other things, if a line from one side of the circle throught its centre and to the opposing side,(its diameter) is equal to one, then its circumference is equal to Pi. In addition the surface area of a circle can be calculated by the formula Pi r2 where r equals the radius of the circle, (half the diameter), Pi times r times r.
What you have there isn't actually a circle, but a stubby pillbox of a "cylinder".Volume of a cylinder = (pi) (R2) (H) = (pi) (15.5)2 (2) = 1,509.54 cubic inches (rounded)
