Answer:
1) Bigger sector = 168.8pi
1) Smaller sector = 56.3pi
2) Bigger sector = 529.9
3) Smaller sector = 176.6
Step-by-step explanation:
1) Bigger sector = [tex]\frac{270}{360}[/tex]×pi×15×15
= 168.75pi
1) Smaller sector = [tex]\frac{360-270}{360}[/tex]×pi×15×15
= [tex]\frac{90}{360}[/tex]×pi×15×15
= 56.25pi
2) Bigger sector = [tex]\frac{270}{360}[/tex]×3.14×15×15
= 529.875
2) Smaller sector = [tex]\frac{360-270}{360}[/tex]×3.14×15×15
= [tex]\frac{90}{360}[/tex]×3.14×15×15
= 176.625
