Question

PLEASE ANSWER! How would I answer the first two questions? My teacher wrote “fraction” so should I leave it as a fraction? If yes how would I leave it as a fraction!

Answer 1

6.
`s = (95 \pi)/(6)~ft`

7.
`A = (50 \pi)/(3)~in.^2`

Explanation:

6.

`s = (n)/(360^\circ) 2 \pi r`

`s = (150^\circ)/(360^\circ) 2 \pi * 19~ft`

`s = (15)/(36) 2 \pi * 19~ft`

`s = (15)/(18) \pi * 19~ft`

`s = (5 * 19)/(6) \pi~ft`

`s = (95 \pi)/(6)~ft`

7.

`A = (n)/(360^\circ) \pi r^2`

`A = (60^\circ)/(360^\circ) \pi * (10~in.)^2`

`A = (6)/(36) \pi * 100~in.^2`

`A = (100 \pi)/(6)~in.^2`

`A = (50 \pi)/(3)~in.^2`
