Answer:

  20π square units

Step-by-step explanation:

The sector area is found using the proportion ...

  sector area / circle area = sector angle / whole circle angle

Multiplying by "circle area", we get ...

  sector area = (circle area)( sector angle / whole circle angle)

  = (100π)(2/5π)/(2π)

  = (100π)(1/5)

  sector area = 20π

. An elevator starts at the 6th floor. It goes up 7 floors twice, and then it goes
Anettt [7]

Well let's see what floor each one lands on and figure out which one is higher.

Something to note:

down = subtracting

up = adding

if something says it's doing something more than once, add it the number of times it's doing that thing. (You can also multiply it by that number but the adding way is a bit easier to understand and explain)

<u>Elevator 1:</u>

6 + 7 + 7 - 10 = 10

<u>Elevator 2:</u>

20 - 5 - 5 - 5 + 12 = 17

Elevator 2 ends on a higher floor (reasoning above)
