There were 22,180 seats in a stadium. There are 85 sections with an equal number of seats in each and the remaining seats are floor level. How many seats are on the floor?

Step-by-step explanation:

There are multiple solutions.

If each section has n seats, the floor has 22,180-85n seats.

22,180/85 ≅ 260.9, so each section has at most 260 seats.

If each section has 260 seats, the floor has 22,180-85×260 = 80.

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!

the answer is 96 degrees

step-by-step explanation:

you have to realize that a line equals 180 degrees
