Radius of circle is 3.39 units

Solution:

Given that,

Area of circle = 36 square units

To find: Radius of circle

The area of circle is given as:

[tex]A = \pi r^2[/tex]

Where, r is the radius of circle

From given,

[tex]36 = 3.14 \times r^2\\\\r^2 = \frac{36}{3.14}\\\\r^2 = 11.464\\\\Take\ square\ root\ on\ both\ sides\\\\r = 3.385\\\\r \approx 3.39[/tex]

Thus radius of circle is 3.39 units
