Answer:
1 unit
Step-by-step explanation:
The circumference of a circle can be found by multiplying the diameter by pi (around 3.14)
If you rearrange this equation to find the diameter, you get:
If you add your numbers into this, you get:
As pi is around 3.14, you essentially end up with d = 3.14/3.14, and because any number divided by itself is equal to 1, we end up with the diameter being 1.

10 small boxes and 11 large boxes were shipped.
Step-by-step explanation:
Given,
Total boxes shipped = 21
Total volume of shipped boxes = 342 cubic feet
Volume of each small box = 10 cubic feet
Volume of each large box = 22 cubic feet
Let,
Number of small boxes = x
Number of large boxes = y
According to given statement;
x+y=21 Eqn 1
10x+22y=342 Eqn 2
Multiplying Eqn 1 by 10
Subtracting Eqn 3 from Eqn 2
Dividing both sides by 12
Putting y=11 in Eqn 1
10 small boxes and 11 large boxes were shipped.
