2. Find the area in square meters of the figure<br> below? Use 3.14 for.<br> 6m
Illusion [34]

Answer:

in order to find the area, we should break up the figure. you can see that in the image we have a quarter of a circle and a square. here are the areas for each of these shapes

square:

area = {x}^{2}

circle:

area = \pi {r}^{2}

but since we only have a quarter of this circle we need to divide the area by 4 so the formula becomes

\frac{\pi {r}^{2} }{4}

now we can plug in our numbers

we are given 6 m for our radius or length of square

the square will be (6)^2 = 36 m^2

now onto our circle

π(6)^2/4 = 28.26 m^2

now add these two shapes together to find the total area = 64.26 m^2

Which function can be used to represent the graphed geometric sequence
11111nata11111 [884]
ANSWER

f(x)=80( \frac{1}{4}) ^{x-1}


EXPLANATION

The term of the sequence are;

80,20,5,...


The first term of the sequence is,

a_1=80



The common ratio is

r =  \frac{20}{80}

r =  \frac{1}{4}

The sequence is given by the formula


f(x)=a_1r^{x-1}


When we substitute the values into the formula we get,

f(x)=80( \frac{1}{4}) ^{x-1}


The correct answer is A
