a sector of a circle has a central angle measure of 60°, and an area of 14 sq inches, what is the area of the entire circle​

Respuesta :

Answer:

area of entire circle = 84 in²

Explanation:

[tex]\sf \dfrac{\theta}{360} *\pi *r^2 = Area \ of \ sector[/tex]

===========

[tex]\sf \rightarrow \dfrac{60}{360} *\pi *r^2 = 14[/tex]

[tex]\sf \rightarrow \dfrac{1}{6}\pi *r^2 = 14[/tex]

[tex]\sf \rightarrow r^2 = \dfrac{14*6}{ \pi}[/tex]

[tex]\sf \rightarrow r = \sqrt{\dfrac{84}{ \pi} }[/tex]

[tex]\sf \rightarrow r = 5.17\ in[/tex]

Area of circle:

[tex]\sf \pi r^2[/tex]

=====

[tex]\hookrightarrow \sf \pi (5.17)^2[/tex]

[tex]\hookrightarrow \sf 84\ in^2[/tex]
