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
Answer:
17
Step-by-step explanation:
a^2 + b^2 = c^2
a^2 = 8^2 = 64
b^2 = 15^2 = 225
64 + 225 = 289
c^2 = 289
c = Square root of 278
c = 17
