Answer:
Step-by-step explanation:
Arc length of the circle is given by,
Arc length =
Area of the sector of a circle =
22). Arc length of the circle having central angle =
= 60°
Arc length =
=
= 7.33 cm
23). Arc length of the circle having central angle = 225°
Arc length =
= 12.5π
= 39.27 km
24). Central angle =
=
= 225°
Area of the sector =
= 43.20 yd²
25). Area of the sector =
= 65.97 yd²
