Answer 2

The radius of circle is 1.633 cm.

Step-by-step explanation:

The area of a circle is:

$Area =\pi r^{2}$

Given:

Area = 8.38 cm²

Compute the value of r as follows:

$Area =\pi r^{2}$

  $8.38=\frac{22}{7}\times r^{2}$

$\frac{8.38\times 7}{22}=r^{2}$

      $r =1.6329\\r\approx1.633$

Thus, the radius of circle is 1.633 cm.
