This answer is incorrect.
The question is asking about the surface area of a circle. The formula for the surface area of a circle is:
PI time the square of the radius.
A = pi x r x r;
So in this case the diameter is given in the problem as 3 meters.
The radius is half of this amount, so r = 1.5 meters
A = 3.141 x 1.5 x 1.5
A = 7.06725
So the first answer of 7 was the best answer
Now let us try another one
Elena wants to sew a border of fringe around a tablecloth for her dining room table. The round tablecloth has a diameter of 6 feet. Approximately how many feet of fringe will Elena need to buy?
