If the diameter of the earth we're squared what would the diameter of the new planet be

Question says that if the diameter of the earth we're squared what would the diameter of the new planet be.

Diameter of the earth is not given so we have to ways to proceed.

Assume that diameter is d then find answer.

Or

Find diameter of the Earth from internet or book then use it to find the answer.

I will go with 2nd choice.

We know that diameter of the Earth is 7917.5 miles.

So take square of that

Hence diameter of the new planet will be 62686806.25 miles.

or

Step-by-step explanation:

We are supposed to find the diameter of a new planet if it has two times the diameter of the earth.

Since, the value of the diameter of earth is not given so checking it from the internet, we get a value of approximately 12,742 km.

So we will take square of this value of the diameter of the earth to see how much will be the diameter of the new planet:

So the diameter of the new planet be or .
