Answer:
The correct option is;
Connect the two circles together using the compass.
Step-by-step explanation:
To draw an inscribed equilateral triangle;
1) Construct the circle
2) The radius of the circle can be drawn from the center of the circle intersecting the circumference
3) With the compass adjusted to the length of the radius, place the compass at the point of intersection of the radius and the circumference and draw arcs around the circumference of the circle
4) Connect every other point where the arc crosses the circumference
5) The figure constructed is n equilateral triangle
Therefore, the correct option is Connect the two circles together using the compass.

Start with
We observe that both fractions are not defined if 
. So, we will assume 
.
We multiply both numerator and denominator of the first fraction by 3 and we sum the two fractions:
We multiply both sides by 
:
We move everything to one side and solve the quadratic equation:
We check the solution:
which is true
<em>If the radius of a sphere is doubled, the surface area becomes four times the original surface area.</em>
