I'm not sure of the vocab you're supposed to use, but I think it's: Manuel Carmen, estoy (I am) muy contento por ellos, pero eso (that) es algo enfermo y no puedo ir.
Hope that helps and is somewhat correct!
Answer:
The combined volume of Mercury and Venus is 9.888*10^11 km³
Step by step solution:
The volume of the planet Venus is about 928000000000 km sq cube:
Vv=928,000,000,000 km³=92.8*10^10 km³
The volume of the planet Mercury is about 6.08*10 to the power of 10:
Vm=6.08*10^10 km³
What is the combined volume of ;ercury and Venus?
V=?
The comined volume of Mercury and Venus is the sum of the two volume:
V=Vv+Vm
V=92.8*10^10 km³+6.08*10^10 km³
V=98.88*10^10 km³
V=9.888*10^11 km³
