There are four parts of a circle, so you have to find out the area of the circle:-
10 cm=Radius
=100
=3.14
3.14*100=314
Now, find the area of the square box:-
Since half the side of the square is 10 cm, the total length of one side is 2*10 which is 20 cm.
Area=S*S
=20*20=400
Now subtract the area of the box from the area of the square:-
400-314= 86
That is the area of the shaded part.
Happy to help you!
Answer:
Step-by-step explanation:
The average rate of change is the slope. However, since this is not a linear function but an exponential one, we cannot determine the slope of the function, only the slope of the secant line that connects the x-values of 4 and 8. In order to do that we need to find the corresponding y-coordinate that goes with each of those x-values and plug them into the slope function. What we will get is a very loose interpretation of the rate of change of population, but that's all we have short of using calculus. It would be a closer estimation if we looked at x values of 4 and 5, or eve 4 ad 4.5. But that's not what we're being asked. So let's get to it.
Sub first 4 in for x and then 8, to get each y value:
to get that P(4) = 2742.16
to get that P(8) = 2937.29
The coordinates for these are (4, 2742.16) and (8, 2937.29)
Plug into the slope formula:
which gives you, in decimal form rounded to the nearest hundredth,
48.78 million.
The interpretation of this value in our situation is that between 1954 and 1958 the population increased 48.78 million people per year.
