Hello,
Let make a rule of three.
For 360° area of the circle is π R²
For 1° ............of the sector .. πR²/360
For 110° ............................... πR²*110/360 =50(units squared)
R²=50*360/(110π)
==>R=6*√(50/(11π))≈7,217137....(units)

Answer:
Area of the sector(A) is given by:
[tex]A = \pi r^2 \cdot \frac{\theta}{360^{\circ}}[/tex]
where,
r is the radius of the circle and [tex]\theta[/tex] is the central angle in degree.
As per the statement:
The area of the sector formed by the 110 degree central angle is 50 units squared.
⇒A = 50 units squared and [tex]\theta = 110^{\circ}[/tex]
Substitute these in [1] and use 3.14 for pi we have;
[tex]50 = 3.14 \cdot r^2 \cdot \frac{110}{360}[/tex]
⇒[tex]50 = 0.959444446r^2[/tex]
Divide both sides by 0.959444446 we get;
[tex]r^2 = 52.1134915[/tex]
⇒[tex]r = \sqrt{52.1134915}[/tex]
Simplify:
r ≈ 7.22 units
Therefore, the radius of this circle is, 7.22 units
