The answer is actually 16, half of 32  1/8 x 1/2 = 2/16 divided by 2/2 = 1/8 but since you don't need to simplify only use the denominator of 2/16 or only need to multiply 8 and 2.

A semicircle has an area of 76.97 squared km. Find it’s radius
shtirl [24]

Answer:

7 km

Step-by-step explanation:

Substitute:

The equation for area of a semi-circle is \frac{r^{2}\pi }{2}

A =  \frac{r^{2}\pi }{2}

76.97 =  \frac{r^{2}\pi }{2}

Multiply by 2 on both sides:

2(76.97) = ( \frac{r^{2}\pi }{2})2

153.94 = r^{2} \pi

Divide by pi on both sides:

153.94 = r^{2} \pi

/pi           /pi

49.03 ≈ r^{2}

Find the square root:

\sqrt{49.03} =\sqrt{r^{2} }

7 = r

5 oranges cost $2. Find the cost of 20 oranges.
Sonja [21]
<h3>Answer:  $8</h3>

===================================================

Work Shown:

(5 oranges)/(2 dollars) = (20 oranges)/(x dollars)

5/2 = 20/x

5x = 2*20 .... cross multiply

5x = 40

x = 40/5 .... dividing both sides by 5

x = 8

20 oranges cost $8

--------------

Another way to approach the problem is to note that the jump from "5 oranges" to "20 oranges" is "times 4".

5*4 = 20

So we'll apply the "times 4" operation to the old cost of $2 to get the new cost being 2*4 = 8 dollars
