A circle has a radius of 5 and a central angle in radians θ = 0.9. Calculate the arc length (s) and area of the sector (A)

The formula for the arc length of a circle (s) is below

s = rθ where θ is in radians

s = | 5(0.9) |

s = | 4.5π |

s =

The formula for the area of a circle sector (A) is below

A = | r^{2}θ |

where θ is in radians

A = | 5^{2}(0.9) |

2 |

A = | 25(0.9) |

2 |

A = | 22.5π |
