The formula is: area = 3.14 (pi) times radius squared.
Exact area of circle: 961*pi square cm
The circumference of a circle with a 31 foot diameter is 97.4 feet, approx.
Circumference of circle: 31*pi = 97.389 inches rounded to 3 decimal places
That will depend on the circumference of the circle which has not been given
Yes it can. If it is a rectangle then the sides would be (7+√31)x(7-√31).
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)
A circle with a radius of 31 cm has an area of 3019.07 square cm.
radius of 31 inches
The circumference of a circle with a radius of 31 meters is about 194.8 meters.
Improved Answer:-Its radius: circumference/diameter = piIts area: pi*pi squared = 31 square cm rounded to nearest integer
3,017.54sq ft
31 feet 5 inches
31x3.1416=circumference
If you mean a circle center at (3, 1) and a radius of 2 then the equation of the circle is (x-3)^2 +(y-1)^2 = 4
Circumference of a circle = (pi) x DiameterDiameter = 2 x radiusCircumference = (pi) x (2 x radius)(2 x radius) = Circumference/piRadius = Circumference/(2 x pi) ==> Over to you.
2*pi*31 square mm or pi*62 square mm
I'm not sure what you mean. If the radius is 5, the circumference is 10pi. (about 31 and a half) If the circumference is 5, the radius is 5 divided by 2pi. (about four fifths)
The volume of the right angled cylinder is = 22/7 * r2 *h where r is the radius of the radius of the circle & h is the height of the cylinder the ans of ur question is 22/7*14*14*31=19096 unit2
