Although the line isn’t there, if you imagine there is one, then you will see that you form a rectangle which is the same line as the semicircle’s diameter.

The area of rectangle is:

⇒ $A = lw$

⇒ $A = (14)(8)$

⇒ $A = 112cm^{2}$

The area of the semicircle;

⇒ $A = \frac{1}{2}\pi r^{2}$

⇒ $A = \frac{1}{2}\pi (7)^{2}$

*Note here that the radius is half the diameter, so it is 7cm, not 14cm

⇒ $A = 76.97cm^{2}$

Finally subtract the two areas;

⇒ $A = 112 - 76.97$

⇒ $A = 35.03cm^{2}$

TIME RE

tester [92]

Answer:

see explanation

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

$\frac{f(b)-f(a)}{b-a}$

Here [ a, b ] = [ 4, 7 ], thus

z = $\frac{g(7)-g(4)}{7-4}$

What is the median of the following string of values?<br>16, 95, 3, 37.97. 13, 27.42, 64, 14

liubo4ka [24]

Answer:

21.71

Step-by-step explanation:

1) you need to order then by the size

3, 13, 14, 16, 27.42, 37.97 ,64, 95

2) if there is an odd amount of numbers then the median would be the center term. but if it an even number then you add the two middle terms together and divide them by 2.

16+27.42= 43.42

43.42 divided by 2=21.71

Hope this helped
