1. Annand Group Title

surface area of a sphere is $4\pi*r^2$ r=radius...

2. Annand Group Title

assuming spherical shape to moon, its radius is 3480/2 km... substitute to find the area

3. lostdove Group Title

can u show me the work like how u got that

4. Annand Group Title

got what?

5. Annand Group Title

area?

6. lostdove Group Title

yeah

7. Annand Group Title

value of pi is approximately 3.14... just substitute surface area=4*(3.14)*(1740)^2 sq.km
