A pie has a diameter of 9 inches each slice of the pie has a central angle of 45 degrees What is the area of each slice of pie class=

Respuesta :

  • Angle=45°
  • Radius=9/2=4.5in

Area of sector

  • Ø/360×πr²
  • 45/360×π(4.5)²
  • 1/8×π(20.25)
  • 7.95in²

option B

Answer:

b

Step-by-step explanation:

The area of a sector is (the angle) over 360 multiplied by pi (radius) squared

This would be 45/360 pi (4.5) squared, resulting in option b.
