The yield per acre will be given by:
[total amount of bushels sold]/[area of the field]
Total amount sold=64100+8120=72220
area=488 acres
thus
72220/488
=147.992~148 bushels per acre
2x2x3=12 12x8=96 so the bale of hay weighs 96 pounds.
Try this solution:
for the circle A: circumference=6π, area=9π
for the circle B: circumference=12π, area=36π
PS. formula for circumference is 'L=2πr', for area is 'S=πr²'.
The answer is 34.05
The total distance (D) is the sum of three distances (d1, d2, and d3).
The distance formula is

Distance 1: Phoenix (–12, –16) to Blythe (–20, –9)<span>:
</span>

Distance 2: Blythe (–20, –9) to Los Angeles (–33, –4):

Distance 3: Los Angeles (–33, –4) to <span>San Francisco (–36, 5)
</span>

<span>
D = d1 + d2 + d3 = 10.63 + 13.93 + 9.49 = 34.05</span>
