12 since 12 is not negative. All absolute values r positive
Answer:
960 km
Step-by-step explanation:
Speed = Distance/Time.
From the question, we are to find the Distance.
The formula for Distance is given as:
Speed × Time.
From the question:
Speed = 960 km/hr
Time = 1 hour
Distance = 960 km/hr × 1 hour
Distance = 960 km
Therefore, the airplane can travel for 960km in 1 hour

Circumference of a circle - derivation
This page describes how to derive the formula for the circumference of a circle.
Recall that the definition of pi (π) is the circumference c of any circle divided by its diameter d. Put as an equation, pi is defined as
π
=
c
d
Rearranging this to solve for c we get
c
=
π
d
The diameter of a circle is twice its radius, so substituting 2r for d
c
=
2
π
r
If you know the area
Recall that the area of a circle is given by
area
=
π
r
2
Solving this for r
r

π
So
r
=

a
π
The circumference c of a circle is
c
=
