Find the area of the circle in the sector.

Area of circle: S =pi*(8^2)=64pi=201.06

Area of sector: S = pi*(8^2)*(225/360)=40*pi = 125.66

The area of sector is 40π km² or 126 km²

Step-by-step explanation:

The picture above is a Major Sector. So you have to use the formula, A = θ/360×π×r² where r represent the radius of the circle :

Let θ be 225°,

Let r be 8 km,

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.

if x = 1, then the answer is 3.5
