3.14*d
3.14*12= 37.68
Rounded to the nearest hundredth would be 37.7
x × 44ft =3564
× = 81
area of the section for a picnic
= 1/2 × 44 × 81
= 1782 ft^2
You need to find the 2 numbers that will estimate to the nearest hundred.
here is your answer 13 x 213
I'm not sure how you obtained -5 as your answer but this is the mathematical explanation. hope this helps!
