Step-by-step explanation:
<u>Circle and Square
</u>
We have a geometric construction as shown in the image below. We can see that

Or, equivalently

The triangle formed by r,h and L/2 is right, because the opposite side of the square is tangent to the circle at its midpoint. This means we can use Pythagoras's theorem:

Replacing h

Expanding squares

Simplifying

Multiplying by 4

Joining terms

Solving for the ratio L/R as required

Answer:
8 tomatoes are required to balance 1 cabbage
Step-by-step explanation:
Given :
Two lemons and seven tomatoes are required to balance one cabbage:
2 Lemons + 7 tomatoes = 1 cabbage (equation 1)
