Answer:
Step-by-step explanation:
The surface area of a sphere (which the earth is considered to be) = 4 pi r^2
pi = 3.14
r = 6340
Area = 4 * 3.14 * 6340 * 6340 = 504856736 square km.
You should either round this to 505,000,000 or express a value in scientific notation.
5.05 * 10^8
46 and 19. 46 x 19 = 874 and 46 - 19 = 27
8. 6m + 3n
11. 8r^3 - r^2
12. 3h^2 + 8
hope this helps !
