Answer:
(a) boxes of cat food had been sold.
(b) boxes of cat food had been sold.
Step-by-step explanation:
From the question,
Polly stacked the tins from five boxes of cat food onto an empty shelf and there were 15 tins of cat food in each box. That is,
5 × 15 tins of cat food were stacked onto the empty shelf.
5 × 15 = 75
Hence, 75 tins of cat food were stacked onto the empty shelf.
Also, from the question,
At the end of the week there were 20 tins left on the shelf and the rest of the tins had been sold, that is
75 - 20 tins had been sold
75 - 20 = 55
Hence, 55 tins of cat food had been sold.
To determine the number of boxes of cat food that had been sold,
Since there are 15 tins of cat food per box, then
we will divide 55 tins of cat food that had been sold by 15 tins of cat food per box
55 ÷ 15 =
Hence, boxes of cat food had been sold

For this case we must find the area of the cookie, knowing that it has a circular shape. By definition, the area of a circle is given by:
Where:
r: It is the radius of the circle
According to the data we have:
Thus, the area of the cookie is:
We have
We round:
Thus, the area of the cookie is
