Answer:
write it out i gotchu den.
Step-by-step explanation:
C
-5.5-11.2
change the subtraction to addition
5.5+11.2= 16.7
ok
degree = 120°
A =67 cm²
d=?
note : diameter= 2×radius
area of a circle = πr²
67=22/7 ×r²
67×7=22r²
469=22r²
r²=469/22
r²=21.32
r=4.62
diameter=2 × radius
d= 2× 4.62
d=9.24
d=9
I hope it helps :)
