Step-by-step explanation:
diameter i.e. d = 12ft
radius i.e r= 6ft
Area of the circle is given by,


Answer:
Solution given:
cscθ -cscθcos²θ
taking common
cscθ(1-cos²θ)
we have
1-cos²θ=sin²θ and cscθ=1/sinθ
now
1/sinθ*sin²θ
=sinθ
so

The formula in computing the circumference of a circle is:
<span>C = 2πr</span>
Where:
r = the radius of the circle
Substituting
the given measurement of radius to the formula:
C
= 2 (π) (7 feet)
C
= 14π feet
Therefore,
the circumference of the circle is 14π ft.
