Answer:
b. 2 cans of ink
Step-by-step explanation:
In order to calculate the number of cans you need to paint the complete wall, you first calculate the area of the wall by using the information about its width and height:
With one can you can paint 10m^2 of wall, with two cans you can paint 20m^2, which is enough to paint the wall of 12.5m^2.
Then, you need only two cans of ink

<span>A 15° sector in a circle has an area of 11.9 m2. What is the area of the circle?
The area of the circle will be found as follows:
the fraction of the sector=15/360=1/24
the area of the circle will be:
area=(fraction of the circle)/(fraction of the sector)*(area of the sector)
=1/(1/24)</span>×11.9
=285.6 m²
