The earth has a radius of 6,380 km. The formula for the volume of a sphere is
V = 4/3
ðx^3, and the formula
for surface area of a sphere is A = 4ðx^2 . Find the volume and surface area of the earth and write the answer in
scientific notation with two numbers after the decimal

  • math - ,

    V = 4/3 π r^3
    A = 4 π r^2

    π = 3.1416

    6,380 = 6.38 * 10^3 (scientific notation)

    Insert values and calculate.
