Answer:
central angle is 1.55 rad
Explanation:
Given data
radius = 14 feet
length = 9 ft
to find out
radian measure of the central angle
solution
we know here arc length and radius
so we will apply here formula for central angle that is
radius = arc × ∅
∅ = radius / arc
put here all these value
∅ = 14 / 9
∅ = 1.55 radian
so central angle is 1.55 rad
This is called thermal energy b.
Each of the particle of the substance is usually in motion and the motion of such produces heat.
And the energy associated with heat is the thermal energy.
