Answer:
21.99 units
164.93 units²
Step-by-step explanation:
given radius r = 15 units
angle of sector = 84°
Length of sector = [tex]\frac{84}{360}[/tex] x 2 x π x r
= [tex]\frac{84}{360}[/tex] x 2 x 3.14 x 15
= 21.99 units
Area of sector = [tex]\frac{84}{360}[/tex] x π x r²
= [tex]\frac{84}{360}[/tex] x 3.14 x 15²
= 164.93 units²
