Question

Please help me! in need of help due tomorrow!​

Answer 1

Explanation:

(1). A = π r²

A = 4 π

Area of shaded region is
`(4\pi *260)/(360)` =
`(26)/(9) \pi` or
`(26\pi )/(9)`

(2). C = 4 π

In this case, the length of the bigger arc and the area of shaded region happen to be the same.

The length of the arc ADB is
`(26)/(9) \pi` or
`(26\pi )/(9)`
