A personal-size pizza has the radius shown in the diagram. Will the pizza fit on a plate with a radius of 10−−−√ inches or a radius of 12−−−√ inches. What is the approximate value of each radius?

Answer:

  • fits on a plate with radius √12
  • √10 ≈ 3.16; √12 ≈ 3.46

Step-by-step explanation:

A calculator can tell you the values of the square roots:

  √10 ≈ 3.16

  √12 ≈ 3.46

The radius of the pizza is larger than √10, so will not fit on that plate. It is less than √12, so will fit on a plate with radius √12.
