Answer:
square kilometers
Step-by-step explanation:
The surface area of a sphere can be found using the formula
. Since the diameter is 3500 km then its radius is half of this. 3500 divided in two is 1,750 units. Substitute r=1,750.

The surface area of the moon is about 38,465,000 square kilometers. Write this is scientific notation using base. 
Answer:
$2,677.72
Step-by-step explanation:
L = 3C
P
4P + 3L = 1,580.62
2L + 5C = 1,340.90
4P + 5L + 3C = ?
2L + 5C = 1,340.90
6C + 5C = 1,340.90
11C = 1,340.90
C = 121.90
121.90 * 3 = 365.70
L = 365.70
4P + 3L = 1,580.62
365.70 * 3 = 1,097.10
4P = 483.52
P = 120.88
C = 121.90
L = 365.70
P = 120.88
4P + 5L + 3C = ?
4(120.88) + 5(365.70) + 3(121.90) = 2,677.72
