Answer:
7 units
Step-by-step explanation:
A=pi*r^2
153.86=3.14*r^2
153.86/3.14=r^2
49=r^2
r=7
Data Input

Procedure:

The answer would be 2747.5 miles
Answer:
x = - 1
Step-by-step explanation:
The equation of the axis of symmetry for a parabola in standard form
y = ax² + bx + c : a ≠ 0 is found using
x = - 
y = - x² - 2x - 5 ← is in standard form
with a = - 1 and b = - 2, thus equation of axis of symmetry is
x = -
= - 1
Equation of axis of symmetry is x = - 1
