Probably too late, but still need to know how to do this.
Formula for the area of a circle: A = πr² [pi times radius(r) squared]
The radius is half of the diameter. [diameter would be a line that would go through the whole circle, the radius would be a line that would stop/end halfway through the circle - see attached image]
They gave you the diameter, which is 3, so divide it by 2 or multiply by 1/2 to get the radius, which will be 1.5.
A = πr² Plug in 1.5 for r
A = π(1.5)² Find 1.5² [or 1.5 x 1.5 = 2.25]
A = 2.25π meters²
