Answer:
The Surface area of the moon is 
Step-by-step explanation:
Given:
Diameter of the moon = 3.8 x 10 to the 8th
To Find :
The surface area of the moon = ?
Solution:
The moon is in the shape of of the sphere .
So the surface area of the moon = surface area of the sphere
The surface area of the sphere = 
Where r is the radius of the sphere
Radius , r = 
r = 
r = 
Now the surface area of the moon with radius r =
is
=> 
=>
=>
=>

Answer:
area of triangle
= 1/2 × base × height
= 1/2 × 3 units × 4 units
= 6 units²
Answer:
6 =v
Step-by-step explanation:
-5(v - 1) = -6- (1 + 3v)
Distribute
-5v +5 = -6 -1 -3v
Combine like terms
-5v +5 = -7 -3v
Add 5v to each side
-5v+5v +5 = -7 -3v+5v
5 = -7+2v
Add 7 to each side
5+7 = -7+7 +2v
12 = 2v
Divide each side by 2
12/2 = 2v/2
6 =v
Answer: I think 91.9
Step-by-step explanation:
If I remember right, all the angles of a triangle add up to 180 degrees. So taking 22.8 + 65.3 = 88.1, then 180 - 88.1 = 91.9
Sorry if that’s not right! I just wanted to take a crack at it.
