1.- In this problem we have to find the area of the circle. We know that the formula to find the area of a circle is: A= πr<span>² </span>Meaning area of the circle= 3.14*radius<span>² Since the radius is equivalent to half the diameter, and we know the diameter is 40, the radius is 40/2 or 20ft Which means the area of this circle is equal to 3.14*20</span><span>² Which is equal to 1256
2.- Here we need to find the radius And since the diameter of the tablecloth is equal to 42+8, to find it we just need to divide 50 by 2 which gives us 25 50/2= 25
3.- This question asks for the area to obtain it we use the formula: </span>A= πr² So... Area= 3.14*25² Which is equal to 1962.5
