OACB is a minor sector. We know that, the area of a sector θ/360° × πr² Therefore, area of sector OACB = 60°/360° × 22/7 (6)² = 1/6 × 22/7 × 6 × 6 = 132/7 cm² See this Video explanation👇😀
OACB is a minor sector.
We know that, the area of a sector θ/360° × πr²
Therefore, area of sector OACB
= 60°/360° × 22/7 (6)²
= 1/6 × 22/7 × 6 × 6
= 132/7 cm²
Let the radius of circle = r Circumference = 22 cm Therefore, 2πr = 22 ⇒ r = 22/2π = 11/π Quadrant of circle subtends an angle of 90° at the center. Therefore, the area of quadrant = 90°/360° × πr² = 1/4 × π(11/π)² = 1/4 × π × 11/π = 121/4π = (121 × 7)/(4 × 22) = 77/8 cm² See here for better understRead more

-The bag contains lemon flavoured candies only. It does not contain any orange flavoured candies. This implies that every time, she will take out only lemon flavoured candies. Therefore, event that Malini will take out an orange flavoured candy is an impossible event.
Hence, P (an orange flavoured candy) = 0
-As the bag has lemon flavored candies, Malini will take out only lemon-flavored candies. Therefore, event that Malini will take out a lemon-flavored candy is a sure event.
P (a lemon-flavored candy) = 1
