Answer:
25.63694268 = r
Step-by-step explanation:
The circumference is
C = 2*pi*r
161 = 2*(3.14) *r
161 = 6.28 r
Divide each side by 6.28
161/6.28 = r
25.63694268 = r
Answer:
-2
Step-by-step explanation:
Y + 6 = 4/5( x + 3)
y + 6 = 4/5x + (3(4))/5
y + 6 = 4/5x + (12)/5
y + 6 = 4/5x + 12/5
y + 6 (-6) = 4/5x + 12/5 (-6)
y = 4/5x + 12/5 (- 30/5)
y = 4/5x - 3.6 ( y = mx + b formula)
4/5 = 0.8
y = 0.8x - 3.6
x = 1
y = 0.8(1) - 3.6
y = - 2.8
x = 2
y = 0.8(2) - 3.6
y = 1.6 - 3.6
y = -2
x = 3
y = 0.8(3) - 3.6
y = 2.4 - 3.6
y = - 1.2
x = 4
y = 0.8(4) - 3.6
y = 3.2 - 3.6
y = - 0.4
x = 5
y = 0.8(5) - 3.6
y = 4 - 3.6
y = 0.4
etc.

Answer:
Option 4
Step-by-step explanation:
Sum of interior angles of a △ = 180°
∴ ∠T + ∠V + ∠U = 180°
⇒ 37° + 63° + X° = 180°
⇒ X° + 100 = 180°
⇒ X° = 180° - 100°
⇒ X° = 80° (D).
