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
Hi there!

The total distance in miles would be 1 1/8 miles.
By using a number line, line up the fractions, so then you could add them both.
Hope this helps :)
