Zimar has to paint a circular wall has a diameter of 12 ft. About how much paint will Zimar need to cover the wall if 1 gallon covers 11 ft?

10.28 gallons to the nearest hundredth.

Step-by-step explanation:

I am assuming you mean 11 square feet.

Area of the wall = π r ^2 where r = the radius.

here the radius = 1/2 * diameter

= 1/2 * 12

= 6 feet.

The area = π 6 ^2

= 36 * 3.1416

= 113.10 ft^2.

So the amount of paint needed

= 113.10 / 11

= 10.28 gallons.
