Lines k and n are perpendicular. if the slope of line k is -6, what is the slope of line n?

a. 6
b. 1/6
c. -6
d. -1/6

For perpendicular lines:
"Their slopes' product is -1"

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!
