The earth equatorial radius = 6.3781×10^6 (metres)

Assuming the sun to be a perfect sphere the volume is given by Volume = (4×pi×R^3)÷3 = 1.08683241×10^21 (cubic metres)

Again assuming the sun to be a perfect sphere the surface area is given by surface srea = 4×piR^2 = 5.110201962×10^14 (square metres)
