251.2 =
(3.14)(r^2)(15)
251.2 =
(47.1) (r^2)
251.2 = (15.7)(r^2)
251.2 ÷ 15.7 = 16 15.7 ÷ 15.7 = 1
16 ≈ r^2
4 ≈ r

Answer:
Step-by-step explanation:
7x-11=4x+4(being vertically opposite angles)
7x-4x=4+11
3x=15
x=15/3
x=5
angle 2+angle1=180 degree(being straight line)
7x-11+angle 1=180
7*5-11+angle 1=180
35-11+angle1=180
24+angle 1=180
angle 1=180-24
angle 1=156 degree
