It is likely D I am not positive
Step-by-step explanation:
we know ,
area of circle =πr^2
hence we get from the figure that the diameter of circle is 19 cm and we can find radius
r=d/2
r=18/2=9cm
area of semicircle =πr^2/2
area of Semi circle equals to =22*(9)^2/7/2
=127.2857143
Answer:
11
Step-by-step explanation:
2w = 2×8 - (-2×3)
2w = 16 - (-6)
2w = 22
w = 11
Answer:
you trying to figure out what is B?
B is isosceles triangles
General form for circle is
(x - a)^2 + (y - b)^2 = r^2
so if center is at (3,-2) we can plug in a and b:-
(x-3)^2 + (y+2)^2 = r^2
Now plug in x = 7 and y =1 (from the point R)
4^2 + 3^2 = r^2
r^2 = 25 making r = 5
so its diameter = 2*5 = 10
