What is the diameter of a cylinder whose cross-sectional area is 706.86 square inches?

🔍 Key Concepts

• Formula for the area of a circle in terms of radius and diameter • How to solve for radius or diameter when given the area • Relationship between radius and diameter (d = 2r)

💭 Think About

• Start with the formula for the area of a circle and plug in the given area, then solve step-by-step for the radius before finding the diameter. • Think about whether you should take a square root at some point in your calculation, and why. • After you find a numerical value for the diameter, compare it to the choices to see which is closest.

✅ Before You Answer

• Be sure you are using the correct formula for area: in terms of radius first. • Double-check your use of π (pi) in the calculation (approximate value). • Confirm that your final number is a diameter, not a radius, before you compare it to the answer choices.
