Find the area of a sector of a circle with radius 7 cm if the angle of the sector is 60°.

  • 1

Using sector area formula (θ / 360) x π x r² with r = 7 cm and θ = 60° gives (60 / 360) x (22/7) x 7² = (1/6) x 154 = 77/3 = 25.67 cm².

    1. Given radius r = 7 cm and sector angle θ = 60°.

      The formula for the area of a sector is:

      Area = (θ / 360) x π x r²

      Substitute the given values using π = 22/7:

      Area = (60 / 360) x (22/7) x 7 x 7

      Area = (1/6) x 22 x 7

      Area = 154 / 6 = 77 / 3 cm².

      In decimal form, 77 / 3 is approximately 25.67 cm².

      Therefore, the area of the sector is 77/3 cm² (or 25.67 cm²).
