Pretty sure it is A. Hopefully this helps and sorry if I am mistaken.
I hope this helps you
Area=1/2.b.c.sinA
Area =1/2.4.3.0,99
Area =5,98
W=A\L
Divide L from both sides
The L in the right cancels out
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.
sin(4π21). Explanation: Notice that this fits the form of the sine subtraction formula: sin(A−B)=sin(A)cos(B)−cos(A)sin(B).
