Answer:
Step-by-step explanation:
<u>Circumference formula:</u>
<u>Use the given value and find the diameter:</u>
- 138 = 3.14d
- r = 138/3.14
- r = 43.94 ≈ 44 yards
<u>Time required to dig across the garden:</u>
18.03 inches
Put the dimensions into the pythagorean theorem, that will give you the answer.
-6p^3(3p^2 +5p -1) = -18p^5 -30p^4 +6p^3
so this is the right answer sure
