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.
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
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
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)
This could be taken three different ways - a circle with a 62 inch diameter, a 62 inch radius, or a 62 inch circumference. For all of these, it helps to first convert 62 inches into feet. 62 inches = 62/12 = 5 1/6 feet. Area is found from the formula A= π∙r² For a 62 inch radius (5.1667 ft), the area will be about 83.863 ft2 For a 62 inch diameter, the radius will be 31 inches (2.58333 ft) and the area will be about 20.966 ft2 For a 62 inch circumference, the diameter will be about 1.6446 ft, the radius will be 0.8223 ft and the area will be about 2.124 ft2
