How many degrees in a circle?
360 degrees are in a circle no matter how big or small the circle is A circle has 360 degrees.
The area of the sector formed by the 110 degree central angle is 50 units squared What is the circumference of the circle?
For A+ 7.22The area of a sector of a circle is proportional to the angle at the center of the sector, with 360 degrees corresponding to the full circle. Therefore, the area of the total circle for which the problem is stated is 50 X 360/110 = about 163.6 square units. The area of a circle is also equal to pi multiplied by the square of the radius of the circle, so that the radius r of this circle equals the square root of 163.6/pi = about 7.217 units. The circumference of the circle is also twice the radius multiplied by pi = 45 units, to the justified number of significant digits (limited by "50").a+ 45.33
What is the area of the sector of a circle?
Suppose the radius of the circle is r units and the sector subtends an agle of x radians at the centre of the circle. ThenArea = 0.5*r2*x square units.If x is measured in degrees, this becomesArea = pi*r2*x/360 square units.
What is the arc length if the measure is 85 degrees and the radius is 13?
360° subtends the complete circle of length 2πr. So, the ratio of 85/360 = A/2πr.......where A is the arc length A/26π = 85/360 A = 85 x 26π/360 = 19.286 units.
What is the circumference of a circle of radius 2.3 units?
A circle with a radius of 2.3 units has a circumference of 14.45 units.
