C = pi * r ^squared
r = is radius
square the radius, multiple by r
or
2 x pi x r
Answer:
No
Step-by-step explanation:
If you mean they are the sides lengths,
33^2+ 56^2 != 66^2
3136 != 4356
Using cosine rule, the length of the required side = sqrt(32^2 + 35^2 - 2 x 32 x 35cos 120)
= sqrt(1024 + 1225 - (-1120))
= sqrt(2249 + 1120)
= sqrt(3369)
= 58.04
Answer:
6
Step-by-step explanation:
They are corresponding angles which means they are congruent or the same.
So:
18x+2=110
-2 -2
18x=108
/18 /18
x=6
