How much will it cost to paint a circular sign with a radius of 4 feet if the painter charges $1.50 per square foot?

Answer 1

$75.40

First, we must find the area. The formula for the area of a circle is #A=pir^2#, and we know from the question that #r=4#.
Therefore, #A=pi(4^2)=color(blue)(16pi)# square feet.
Since the painter charges #$1.50# per square foot, he would charge a total of #16pi*1.50=color(red)($75.40)#.

Answer 2

$75.39

The area of a circle is given by the formula #pir^2#. Plugging the radius into the equation, we get: #pi times 4^2=16pi, or 50.26ft^2#
If the sign costs $1.50 per square foot, then the cost for the sign is: #50.26 times $1.50 =$75.39#

Answer 3

The cost to paint a circular sign with a radius of 4 feet would be 24,calculatedusingtheformulafortheareaofacircle(πr2)multipliedbythecostpersquarefoot(24, calculated using the formula for the area of a circle (πr^2) multiplied by the cost per square foot (1.50). So, the cost would be π * (4^2) * 1.50,whichequals1.50, which equals 24.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
