Answer: 12π
Solution: The circumference of a circle is its diameter multiplied by π. If we say that P is the length of the pufferfish, then we can then say that the diameter is 12P, so the circumference is 12Pπ. If we divide out the length of the pufferfish, we find that the circumference is 12π times the length of the pufferfish.
Answer: 440 blue-ringed octopuses
Solution: A pound is 16 ounces, so it takes 16 ÷ 4 = 4 blue-ringed octopuses to make up a pound. So, 4 × 110 = 440 blue-ringed octopuses weigh the same as a 110-pound giant pacific octopus.
