The diameter of circle j is 18 cm. the diameter of circle k is 31 cm. which circle has the greater area and by how much

Circle K has a greater area and it is higher than circle J by 500.045 square centimeter

Solution:

The area of circle is given as:

Where "r" is the radius of circle

Also, Radius is given by:

Given that,

Diameter of circle J is 18 cm

Therefore,

Substitute r = 9 in area formula

Thus area of circle J is 254.34 square centimeter

Diameter of Circle K is 31 cm

Substitute r = 15.5 in area formula

Thus area of circle K is 754.385 square centimeter

On comparing the area of circle J and circle K, we find the area of circle K to be higher

Area of circle K - Area of circle J = 754.385 - 254.34 = 500.045

Thus circle K has a greater area and it is higher than circle J by 500.045 square centimeter

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.
