Answer 1

1) Bigger sector = 168.8pi

1) Smaller sector = 56.3pi

2) Bigger sector = 529.9

3) Smaller sector = 176.6

Explanation:

1) Bigger sector =
`(270)/(360)`×pi×15×15

= 168.75pi

1) Smaller sector =
`(360-270)/(360)`×pi×15×15

=
`(90)/(360)`×pi×15×15

= 56.25pi

2) Bigger sector =
`(270)/(360)`×3.14×15×15

= 529.875

2) Smaller sector =
`(360-270)/(360)`×3.14×15×15

=
`(90)/(360)`×3.14×15×15

= 176.625
