Find area around the circle with a radius r of 6 ft. round off your answer to one decimal point

I'm going to assume you mean enclosed by the circle. If this is wrong, either use a comment to correct me or tell me what encloses the circle.

Area = pi*r^2
Area = 3.14 * 6^2 feet squared.
Area = 3.14 * 36
Area = 113.09 ft^2 or 113.1 ft^2

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)
