`        what is the answer of the given question,in the picture uploaded?? `
7 months ago

```							y= x^2/a^2*sqrt(2ax – x^2)=  x^2/a^2*sqrt(a^2 – (x – a)^2)to find the area we integrate y from points where y equals zero which are x=0 and x=2a. note that this integral can be solved by putting x – a=y and then using standard results for integrals of sqrt(a^2 – y^2) and y*sqrt(a^2 – y^2). however, for y^2*sqrt(a^2 – y^2) you will have to put y= asinz and it will turn into integral of sin^2z*cos^2z= (sin2z)^2/4. now put 2z=u and write sin^2u= (1 – cos2u)/2. on integrating the above term you shall find it is 5pia^2/8now divide it by pia^2so ratio equals 5/8kindly approve :)
