Question

Help me with this hard question if u get it right then...

Answer 1

`(13\pi )/(2)` cm^2

Explanation:

im a highschool student but we are doing this stuff and this is how i learned it: calculate the area of the larger sector (
`(64\pi )/(6)`) and subtract the smaller sector(
`(25\pi )/(6)`) from it to get
`(39\pi )/(6)` which can be simplified to
`(13\pi )/(2)`.
