Find the area of the figure. Round to the nearest tenth if necessary.
baherus [9]

Hello!


First of all, let's find the triangle. As we can see, it is eight units long and four units tall. We can use the triangle formula and half the product.


4(8)=32

32/2=16


Now we need to find the area of the semicircle. We can use circle formulas and half our final answer. We will find the area using A=\pir².


We know that the diameter of this circle is eight. Therefore our radius is 4.


A=4\pi²

A=16\pi


Now we multiply.


16\pi≈50.27


Now we add our triangle.


50.27+16=66.27


The nearest answer to this is B)66.2. It may have been a bit over as we used \pi, not 3.14.


I hope this helps!

The average daily high temperature in Seattle is modeled by the function T = –15 cos(πm/6)+ 61, where T is the temperature in °F
Sliva [168]

Answer:

m = 6

Step-by-step explanation:

T = -15cos(\frac{\pi m}{6}) +61

76 = -15cos(\frac{\pi m}{6}) +61

76-61 = -15cos(\frac{\pi m}{6})

15 = -15cos(\frac{\pi m}{6})

\frac{15}{-15}  = cos(\frac{\pi m}{6})

-1  = cos(\frac{\pi m}{6})

cos^{-1}( -1)  = \frac{\pi m}{6}

\pi  = \frac{\pi m}{6}

6\pi  = \pi m

m = 6
