A room covers 299.6 square feet. A painter paints the room in three days. The first day he covers 2/7 of the area. The next day
Trava [24]

Answer:

<em>On day the he covers </em>128.4 ft²

<u>Step-by-step explanation</u>:

Lets first figure out how much he has done so far

To figure out how much he does we can use a proportion

Set up a proportion for first day

2/7 = x/299.6

Solve the proportion

2×299.6÷7 = 599.2/7 = x

x = 85.6

<em>He covered 85.6 sq/ft on day 1</em>

Find day two

85.6 * 2 = 171.2

Find how much is left to do on day 3

299.6-171.2 = 128.4 ft²

If the area of a circle is 121pie square units, what is the diameter
velikii [3]
Since you are given the area, we can solve for radius with this equation:
A_c = \pi r^2
r = \sqrt{ \frac{A_c}{ \pi } } = \sqrt{ \frac{121 \pi }{ \pi } } = \sqrt{121} = 11

The radius is 11, so the diameter must be 2 times that, which is 22. With the correct units, the answer is 22 units²
