Answer:
19,27 cm^2
Step-by-step explanation:
area of triangle = (6 x 3)/ 2 = 9 cm^2
circle area : 3^2 x 3,14 = 28,27 cm^2
area of shaped region = 28,27 - 9 = 19,27 cm^2
Best option would be either B or C
Answer:
(A) 
Step-by-step explanation:
Given:
Frequency of the wave (f) = 
Speed of the wave (v) = 
The wavelength equation of the wave is given as:

Here, 
Now, plug in the given values and simplify.

Therefore, the wavelength of the wave is option (A) 
Range is output or y values
(x,y)
just the 2nd number of each pair
so it is 2,4,-5,-3
B is answer
