A circle has an area of 36 m2. What is the area of a 40 sector of this circle?

Mathematics

The ratio of the area of the sector (S) to the area of the entire circle (C) is equal to the ratio of the angle subtended to form the sector (As) to the angle for the whole revolution (Ac)
                                  S / C = As / Ac
Substituting the given,
                                  S / 36 m² = 40 degrees / 360 degrees  
Solving for S gives, S = 4. Thus, the area of the sector is 4 m².

w = (-m+y)/y

Step-by-step explanation:

y-wy = m

-wy = m-y

Eighty, decreased by three times a
Marina86 [1]

Answer:

The number is 9.

Step-by-step explanation:

Lets write this as an equation first. We'll substitute the number for the variable <em>x</em>.

80 - 3x = 5x + 8

First, let's add 3x to both sides.

80 - 3x + 3x = 5x + 3x + 8

80 = 8x + 8

Next, let's subtract 8 from both sides.

80 - 8 = 8x + 8 - 8

72 = 8x

Finally, let's divide both sides by 8.

72/8 = 8x/8

9 = x

<em>"x" is 9.</em>

<em>So the secret number is 9.</em>
