2 3/4 + 4 3/4
= 6 6/4
= 7 2/4
= 7 1/2
The answer is option A. I believe
Answer:
The area of this sector is 224*pi cm² or approximately 703.72 cm²
Step-by-step explanation:
In order to calculate the area of a sector for which we have an angle in radians, we need to apply a rule of three in such a way that pi*r² is related to 2*pi radians in the same proportion as the given angle is related to the area of the sector we want to find. This is shown below:
2*pi rad -> pi*r² unit²
angle rad -> sector area unit²
2*pi / angle = pi*r² / (sector area)
2*pi*(sector area) = pi*r²*angle
sector area = [pi*r²*angle]/2*pi
sector area = r²*angle/2 unit²
Applying the data from the problem, we have:
sector area = [(16)²*(7*pi/4)]/2 = [256*(7*pi/4)]/2 = 64*7*pi/2 = 32*7*pi = 224*pi
sector area = 224*pi cm²
sector area = 703.72 cm²

Answer:
No
Step-by-step explanation:
The coordinates in an ordered pair are listed (x,y). So, in (8,3) The 8 is the x coordinate and the 3 is the y coordinate. Plug those numbers into the equation and see if it makes a true statement. If it does, then that point is on the line and it is a solution
y = 17x + 7
3 = 17(8) + 7
3 = 136 + 7
3 
143, so this point is not a solution
