0.1 i guess ok so try my question but im not 100 sure its correct
Assuming we have parallel lines, we can solve for x.
Since a = 3x - 10 (vertically opposite angles are equal),
3x - 10 = 2x + 15 (alternate angles are equal)
x = 25
Hence, angle a = 3(25) - 10 = 65°
The formula of circumference: 兀×diameter
In this case:
3.14×11
=34.54cm
Nearest hundreth = 2 demical places
Therefore, the answer is 34.54cm.
Hope it helps!
