The circumference of a circle can be found with this equation:

C = 2\pir


"r" is the radius, which is half of the diameter.

The diameter is 20.

20 ÷ 2 = 10

Your radius is 10. Now that you know the radius, you can plug it into the equation:


C = 2\pir

C = 2\pi(10)  Multiply 2 and 10 together

C = 20\pi


Your circumference is:

20\pi inches  or  62.8318530718 inches(you should round it if you want lol)

The area of a rectangular horse pasture is 268,500 square yards. The length of the pasture is 5 yards less than three times the
Setler79 [48]

Answer:  width = 300

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

Area (A) = Length (L) x width (w)

Given: A = 268,500

           L = 3w - 5

           w = w

268,500 = (3w - 5) x (w)

268,500 = 3w² - 5w

            0 = 3w² - 5w - 268,500

            0 = (3w + 895) (w - 300)

   0 = 3w + 895        0 = w - 300

  -985/3 = w             300 = w

Since width cannot be negative, disregard w = -985/3

So the only valid answer is: w = 300

Let's say "m" is the manufactoring cost per drill (in dollars).

Then the manufactorer sells it for $4 more, so this would be:

    m+4

Then the chain store sells it for 140% of the price is paid the manufactorer, so this would be "140% of (m+4)" which translates to "1.4•(m+4)" or more simply:

    1.4(m+4)

P(m) = 1.4(m+4), where m is the initial manufactoring cost (in dollars).

Simplifying, you could rewrite this as:

     P(m) = 1.4m + 5.6
