Answer:
Larger shaded area = 48pi m^2 and
the small circle has area 4pi m^2.
If you require the as decimal values they are
150.80 m^2 and 12.57 m^2 to the nearest hundredth.
Step-by-step explanation:
The area of the whole circle = pi r^2 = pi 8^2 = 64pi.
The area of the middle sized circle = pi 4*2 = 16pi.
So the area of the larger shaded region
= 64pi - 16pi = 48pi m^2.
The area of the small circle = pi r^2 = 2^2 pi = 4pi m^2.
The system of equations is
3d+7p=61.25
12d+9p=107.25
Answer:
Step-by-step explanation:
By definition, a relation is a function if and only if each input value have one and only one output value.
The input values are the x-values and the output values are the y-values.
Given the function f(x):
You need to substitute 
into this function:
And now you must evaluate in order to find the corresponding output value.
You get:
The function g(x) is:
Then, you need to substitute 
in the function:
And finally you must evaluate in order to find the corresponding output value. This is:
Answer:
3/5
Step-by-step explanation:
cos A = adjacent side / hypotenuse in a right triangle
cos A = 24/40
Cos A = 6/10
cos A = 3/5
