Answer:

Step-by-step explanation:
<h2>Given that :</h2>
- The radius of a circle is 2.9 in.
<h2>to find :</h2>
- Find the circumference to the nearest tenth.
<h2>formulas used :</h2>
- circumference = 2 × π × r
where,
<h2>explanation :</h2>
⟼ c = 2πr
⟼ c = 2 × 22/7 × 2•9 inches
⟼ c = 2 × 3•14 × 2•9 inches
⟼ c = 6•28 × 2•9 inches
⟼ c = 18•21 inches.
<h2>Round to the nearest tenth :</h2>
⟼ c = 18•21 inches
⟼ c = 20 inches
∴ circle circumference is 20 inches .
Answer:

<h2>4x-5y+32=0 is the right answer.</h2>
Well 746÷40=18.65 so would that be 18?
I don't know if you still need help. but the answer is the first one.
Divide the number of blocks by number of people
In this case 5/6 = 0.83 blocks or each person will get 0.83 or 5/6 of a block
