Answer:
10
Step-by-step explanation:
pi is 3.14...
pi - 1 is 2.14...
question becomes 1<2.14x and 2.14x < 10
1/2.14 < x, 0.46... < x
x < 10/2.14, x < 4.67...
combining
0.46< x < 4.67
x can be 1, 2, 3, 4
Area of the board divided by the time
2 x 3 = 6ft^2
15/6= 2.5mins
I Think it would either be D or C
(I’m not sure, let me know if I’m wrong)
