Fisrt is solve the distance of the segments using distance
formula
Distance =sqroot[(x2−x1)^2+(y2−y1)^2]
So ditance of RS = 5
ST = 8.49
TR =6.08
The using herons formula
Area = sqrt ( s ( s-a) ( s-b) ( s-c) )
Where s s = 1/2 ( a + b + c )
And a, b , c are length of the sides
S = 9.785
Area = 14.99
I think the answer is 7 not sure what u were trying to dk with the comma
I am 100% sure it is A. I did the test and it showed it was A.
Please leave a thanks.
Answer:
area of semicircle only = 113.43 mm²
total area = 185.43 mm²
Step-by-step explanation:
(8.5²)(π)(0.5) = 113.43 mm²
(12)(12)(.5) = 72 mm²
72 + 113.43 = 185.43 mm²
