Questions and Answers

What does 'r' represent in the formula for the area of a circular sector?

  • Diameter of the circle
  • Radius of the circle (correct)
  • Circumference of the circle
  • Central angle of the sector

What is the formula to find the area of a circular sector?

  • A = (1/2) * Ï€ * r^2 * θ
  • A = r * θ
  • A = 2 * Ï€ * r * θ
  • A = (1/2) * r^2 * θ (correct)

If the central angle of a circular sector is given in degrees, what should be done to use it in the area formula?

  • Convert it to radians by adding Ï€ to the angle
  • No conversion is needed
  • Convert it to radians by multiplying by 180/Ï€
  • Convert it to radians by multiplying by Ï€/180 (correct)
