Answer:

area of entire circle = 84 in²

Step-by-step explanation:


\sf (\theta)/(360) *\pi *r^2 = Area \ of \ sector

===========


\sf \rightarrow (60)/(360) *\pi *r^2 = 14


\sf \rightarrow (1)/(6)\pi *r^2 = 14


\sf \rightarrow r^2 = (14*6)/( \pi)


\sf \rightarrow r = \sqrt{(84)/( \pi) }


\sf \rightarrow r = 5.17\ in

Area of circle:


\sf \pi r^2

=====


\hookrightarrow \sf \pi (5.17)^2


\hookrightarrow \sf 84\ in^2
