Question

Perimeter with radius 14

Answer 1

`360^o-150^o=210^o\\\\(210^o)/(360^o)=(7)/(12)`


`P_(LQM)=(7)/(12)\cdot2\pi\cdot14=(7)/(3)\pi\cdot7=(49\pi)/(3)\ cm`


`P_(QRP)=(1)/(2)\cdot14\pi=7\pi\ cm`


`P_F=(49\pi)/(3)+7\pi+3\cdot14\approx(49)/(3)\cdot(22)/(7)+7\cdot(22)/(7)+42=166(2)/(3)\ cm^2`
