637 is the answer because our value is 980 we all know the unknown value with x for the step above 980 and 100% and 65% is the result in a pair of a simple equations
-m-4=-13
-m=-13+4=-9
m=9

Answer:
The correct option is;
x = 1
Step-by-step explanation:
The parameters given are;
Location of circle center = 1 on the x axis
Radius of circle = 1
Required operation on circle = Revolving to create a sphere
To form a spherical shape by the rotation of a circular figure involves rotating the circular figure about a line passing through the center of the circle
Therefore, to form a sphere, the circle should be about a line that passes through x = 1
Hence, the circle should be rotated about the line x = 1.
