Using the pi key on your calculator, find the circumference of the earth in meters. round your answer to a reasonable degree of precision. write both the standard form and scientific notation.

40.2×10^6 m ( this is in scientific notation )

4.02×10^7 m (this is in standard form

Step-by-step explanation:

Radius of earth is 6400 km or 6400× 1000 =6400000m =6.4×10^6 m

circumference  C is given by formula C = 2πR WHERE C IS CIRCUMFERENCE AND R IS RADIUS

C = 2×π×6.4×10^6

C = 40.2×10^6 m ( this is in scientific notation )

C= 4.02×10^7 m (this is in standard form )
