Question

the surface areas of jupiter and earth are approximately 6.0x10^10 km 2 and 5.1x10^8 km 2. about how many times greater is jupiter’s surface than earth's surface area
A. 1.2 times
B. 21 times
C. 100 times
D. 120 times

Answer 1

Answer:

D . about 120 times

Lets say that A₁ is the surface area of Jupiter and A₂ is the surface area of Earth

You can find out how much bigger an amount is from another by taking the ratio of them

For example

If we take A₁/A₂

Then we will get a certain value .. lets say that value is k

so A₁/A₂=k

or A₁ = kA₂ ( multiplying both sides by A₂)

This means that the value of A₂ is k times more than A₁

In this case A₁= 6 x 10^10 and A₂ = 5.1 x 10^8

So, A₁/A₂ ≈ 117.65

• or A₁ ≈ 117.65A₂
• or A₁ , jupiter has about 120 times more area than A₂ , earth

Hope this helps :)
