The area of a circle is PiR^2.
Since we know the radius, 1, we can square it and then multiply it by Pi.
Your answer is 3.14, since 1^2 is 1, and 3.14 x 1 = 3.14

It is given in the question that
Anna buys 12 pens and 20 pencils for a total cost of $16. One pen costs $0.40 more than a pencil.
Let the cost of pencil is $ x .
Therefore cost of pen is

According to the question

Distributing 12 and combining like terms, we will get

Therefore cost of pencil is $0.35 and cost of pen is
