We have been given that the surface area of the earth is approximately 197000000 square miles.
Also the land area of the earth is given by 58000000 square miles.
Therefore, the fraction of the earth surface is land is given by

On simplifying it, we get

Answer:
Step-by-step explanation:
Let the ends of the given segment are A and B.
Coordinates of A → (8, 6)
Coordinates of B → (12, 12)
If a point (x, y) is dilated by a scale factor 'k' about the origin, rule to be followed,
(x, y) → (kx, ky)
If k = 
(x, y) → 
By this rule coordinates of the image points of A and B will be,
A(8, 6) → 
→ A'(5.3, 4)
B(12, 12) → 
→ B'(8, 8)
Now we can get the image of segment AB after dilation by a scale factor of
.
One is 3pi/2 - 2pi = -pi/2
also -7pi/2
Radius on a coordinated plane
The answer of the question is B
