Diameter of MOON=2r
Radius of MOON =r
Radius of EARTH = 4r.
Ratio of their surface areas= (4*22\7*r*r)\(4*22\7*r.*r.)
=r*r\r.*r.
=r*r\4r*4r
=1\16
=1;16

Everyone wants a teacher like him. But. Every teacher needs a student who can study like we do in YouTube 💀

16:42 sir radius was 7/2 but you wrote 7/4.
Otherwise the lesson was awesome and it helped me alot. Because of you sir I scored 49marks out of 50. Thanks a lot.

Sir the session was very awesome but to recheck my answers i wanted to ask that are all the answers for the questions of spheres and hemispheres in the value of non terminating recurring or non terminating non recurring (except for some)??
Plz answer sir 🤩🤩

Sir we can take directly radius in square.. Because in formula there is r square.. We can take it as it is.
