adius of the circle?
A. 18
B. 6
C. 12
D. 36​

Answer 1

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:

`A = \pi r^2`

Where, r is the radius of circle

From given,

`36 = 3.14 * r^2\\\\r^2 = (36)/(3.14)\\\\r^2 = 11.464\\\\Take\ square\ root\ on\ both\ sides\\\\r = 3.385\\\\r \approx 3.39`

Thus radius of circle is 3.39 units
