An airplane from Johannesburg, South Africa is starting its decent to JFK Airport. If the plane descends towards the ground at an average rate of 1,200 feet per minute, then what rational number represents its change in altitude after 17 minutes of descending?

-20,400

Step-by-step explanation:

if 1min=-1,200 then

-1,200*17min=-20,400.

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!

answer is:

1.75 pounds
