The angle x is half the sum of the intercepted arcs, PQ and NO.
... (1/2)(65° + 45°) = 55° = x° = m∠PMQ
Answer:
Area of shaded region = 329.70 cm²
Step-by-step explanation:
Area of a circle = πr²
Area of bigger circle = 3.14 × 11²
= 3.14 × 11 × 11
= 379.94 cm²
Area of smaller circle = 3.14 * 4²
= 3.14 × 4 × 4
= 50.24 cm²
Area of shaded region
= Area of bigger circle - Area of smaller circle
= (379.94 - 50.24) cm²
= 329.70 cm²
