Find the area of a circle with radius, r = 6.81m. Give your answer rounded to 2 DP.

To solve for the area of the circle, we can use the following formula:

A = πr^2

Given the radius of 6.81m,

A = πr^2

A = π (6.81)^2

A = π(46.376)

A = 145.69m^2

The first one, i believe, would be correct. all the others have one thing in common, and that's that they have repeating numbers. in the second one, x and y have repeating 6's and 3's, and in the third, x and y have repeating 6's as well. in the last one, there are repeating 3's. the first one has no repeating numbers.
