we are given
we have to find theta
so, firstly we can write sin in terms of cos
now, we can set it equal
Since, both sides are cos
so, we can set angles equal
now, we can solve for theta
we get

Answer:
<h2>17.2cm^2</h2>
Step-by-step explanation:
step one:
The question did not give the area of the pan and the number of biscuit
so let assume an are of 80cm^2 of the pan and the number of biscuit is 20
the diameter of each biscuit is 2cm
the radius is 2cm
The expression for the area is
A=πr^2
A=3.14*1^2
A= 3.14cm^2
the total area covered by the biscuit is
=3.14*20
=62.8cm^2
the area not covered is
=80-62.8
=17.2cm^2
