The mean radius of a planet is 6.91 × 10^6 m,
and that of its moon is1.42×10^8 cm.
From this data calculate the ratio of the
planet’s surface area to that of its moon.
Thank you for the opportunity to help you with your question!
The S.A of a sphere is 4piR^2
Hence planet's s.a is 4*22/7*6.91*10^6m*6.91*10^6m= 6.0026*10^14msquare
Hi, I am sorry the site had a problem, I had to submit the incomplete answer first. To find the ratio, we now divide the moon's surface area over the earth's surface area.
Hence the ratio of the earth's S.A to the moon's is 1:23.69
