Which conic section does the equation below describe?

a. hyperbola
b. circle
c. ellipse
d. parabola

Option C. Ellipse

Step-by-step explanation:

The general equation of an ellipse has the following form:

Where the point (h, k) is the center of the ellipse

In this case we have the equation

Note that its shape matches that of a ellipse with center (9, -2)

Therefore the answer is the obtion C

then, the surface area of the sphere shown in the image is: 256π sq. units!

step-by-step explanation:

the lateral surface area of a sphere is 2πrh where h=2r.

then:

surface area = 4πr^2.

in this case, r=8 units ⇒ surface area = 4π(8 units)^2. = 256π sq. units!

then, the surface area of the sphere shown in the image is: 256π sq. units!
