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)
A 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
There are 360 degrees in a circle so it will be 1/3 of pi*62 square units
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)
