Answer:

15 cm.

Step-by-step explanation:

It is given that,

Central angle =\dfrac{7\pi}{10}

Arc length = 33 cm

Formula for arc length :

s=r\theta

where, s is arc length, r is radius and \theta is central angle in radian.

Substitute s=33 and \theta=\dfrac{7\pi}{10} in the above formula.

33=r\left(\dfrac{7\pi}{10}\right)

Multiply both sides by 10.

330=7\pi r

Divide both sides by 7\pi.

\dfrac{330}{7\pi}= r

Put \pi=3.14

\dfrac{330}{7(3.14)}= r

15.0136= r

r\approx 15

Therefore, the radius of the circle is 15 cm.
