If diameter of a circle is twice as large as the diameter of a smaller circle, What
is the ratio of area of larger circle to area of smaller circle?

Kindly solve this question in an understandable way.

The ratio of area of larger circle to area of smaller circle is 4:1

Step-by-step explanation:

Area of circle A=πr², d(diameter) = 2r(radius)

Area  of larger circle = πR²

Area  of smaller circle = πr²

Diameter of larger circle  = 2 diameter of smaller circle

D =2 d

2R =2*2r

2R = 4r divide by 2

R =2r

Area  of larger circle = πR²=π(2r)² = π*4r²

Area  of smaller circle = πr²

π*4r²/ πr² =4/1

see below

Step-by-step explanation:

Smaller circle

radius = r

A = pi r^2

Larger circle

radius = 2r

A = pi (2r)^2 = 4pi r^2

larger area / smaller area

4 pi r^2 / pi r^2

4/1

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.
