Answer:
7.74 feet²
Step-by-step explanation:
radius of circle r = 6/2 = 3
area of circle A = π × 3² = 9π = 28.26
area of square = 6² = 36
Remaining board area = 36-28.26 =7.74
Any number you can write completely is a rational number. Any decimal number with a repeating decimal fraction is also a rational number.
If the number of digits goes on forever without repeating, it is an irrational number.
Of the numbers listed, √3 and π are irrational. The remaining numbers are rational. ("The symbol π" is not a number; it is a symbol. It conventionally stands for an irrational number.)
