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 area of a sector with a radius of 8 and an arc of 290 degrees?
Area of the circle = pi*82 = 201.0619298 square units Area of the sector = 290/360 of 201.0619298 = 161.9665546 or about 162 square units
What you called a circle has 360 of these units?
A circle's circumference has 360 degrees around it.
How many degrees are in a circle with a diameter of 10 units?
A circle has 360 degrees, whatever its diameter.
What is the circumference of a circle whose arc length is 19.68 and degrees is 94?
The circumference will have 360 degrees. So the arc is 94/360 of the whole circle. That is, the whole circle will be 360/94 of the arc length. So the circumference of the shole circle is 19.68*360/94 = 75.37 units (to 2 dp)
What is the circumference of a circle with an arc of 90 and an angle of 81?
90*360/81 = 400 units of length.
The area of the sector formed by the 110 degree is 50 units what is the radius of the circle?
If you mean a sector with an arc of 110 degrees and an area of 50 square units Area of all the circle: 360/110 times 50 = 163.'63' square units Radius of the circle is the square root of 163.'63'/pi = 7.2171377402 So the radius of the circle is about 7 units
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.
Find the area of a 120 degree sector of a circle with a radius of 6?
There are 360 degrees in a circle so it will be 1/3 of pi*62 square units
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 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 a sector of a circle that has an arc measure of 75 degrees and a diameter of 15.75?
Area of the circle = pi*7.8752 = 194.8278319 square units Area of sector = 75/360 times 194.8278319 = 40.58913165 square units
How do you convert degrees from a circle graph into numbers?
360 degrees = Total number, T. So a sector of x degrees is equivalent to x*T/360 units.
What is the radius of a circle with a degree of 240 and sector area of 10?
240 deg gives a sector area of 10 sq units so 360 deg would give a sector area of 10*360/240 = 15 sq units ie the area of the whole circle is 15 sq units or π*r2 = 15 so that r = 2.1851 units (to 4 dp)
What do radians and degrees have in common?
They are both units in the measure of an angle. There are 360 degrees in a full turn of a circle. There are 2 pi (radian measure) in a full turn of a circle.
