Answer:
D)
Step-by-step explanation:
49 degrees + 86 degrees = 135 degrees
line QT=180 degrees
135 degrees + 45 degrees = 180 degrees
Just make 1 3/4 an improper fraction and multiply by 4:
1 3/4 = 7/4
7/4 * 4 = 7
Area= pi x r^2
hence,
pi x r^2 = 36 x pi
=> r^2=36
=>r= root over 36 = 6
in short...the radius is 6
