How many linear feet in a 31 foot diameter circle?
The circumference of a circle with a 31 foot diameter is 97.4 feet, approx.
Average chest circumference in 2 year old?
31 inches
What is the measure of an arc that is intercepted by an inscribed angle of 31 degrees?
That will depend on the circumference of the circle which has not been given
If angle ABC measures 124 degrees What is the measure of arc AC'?
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)
What is the exact area of a circle with a radius of 31 cm?
The exact area of a circle can be calculated using the formula A = πr^2, where A is the area, π is a constant approximately equal to 3.14159, and r is the radius. Plugging in the radius of 31 cm, the area would be A = π(31 cm)^2 = π(961 cm^2) = 961π cm^2. Therefore, the exact area of a circle with a radius of 31 cm is 961π square centimeters.
