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. 
The answer too your question is 100
Area is 50 m^2
5 x 3 = 15
7 x 5 = 35
35 + 15 = 50 m^2
Answer:
Y= 43, x=137, z=137 total is 360
Answer:
y = 51.32º
Step-by-step explanation:
z = 180 - 47 - 90
z = 43º
sin43 = opp/hyp
sin43 = 35/y
y = 35/sin43
y = 51.32º
