The cross-section of a sphere is a circle . The area of a circle can be calculated by the formula A= Where r is the radius of the circle.
Given :
Solving for r we have:
Or r= 10.
The area of a sphere is calculated by the formula :
Substituting r value we have:
SA=
The total surface area of this sphere is 400π .
Answer:
Step-by-step explanation:
Plug in the 6 to the equations. Since B is the midpoint of AC, then both should be equal once plugged in [and solved].

Answer:
the solution for x will be given by {x| -13 < x < 13}
Therefore the correct option is B.
Step-by-step explanation:
i) given that |x| < 13
ii) therefore x < 13 for positive values of x
iii) for negative values of x we have -x < 13
therefore x > -13
iv) from ii) and iii) above we can conclude that the solution for x will be given by {x| -13 < x < 13}
Therefore the correct option is B.
