We have been given that in a circle an arc length 10 is intercepted by a central angle of 2/3. We are supposed to find the radius of the circle.

We will use arc-length formula to solve our given problem.

[tex]l=r\theta[/tex], where,

[tex]l[/tex] = Arc length,

[tex]r[/tex] = Radius,

[tex]\theta[/tex] = Central angle corresponding to arc length.

Upon substituting our given values in arc-length formula, we will get:

[tex]10=r\cdot \frac{2}{3}[/tex]

[tex]10\cdot \frac{3}{2}=r\cdot \frac{2}{3}\cdot \frac{3}{2}[/tex]

[tex]5\cdot \frac{3}{1}=r[/tex]

[tex]15=r[/tex]

Therefore, the radius of the given circle would be 15 units.
