Answer

Explanation:

Step1: Identify the shape approximation

An onion can be approximated as a sphere. The diameter of the onion is approximately (d = 3.5) inches, so the radius (r=\frac{d}{2}=\frac{3.5}{2}=1.75) inches.

Step2: Use the surface - area formula for a sphere

The surface - area formula of a sphere is (A = 4\pi r^{2}). Substitute (r = 1.75) into the formula: (A=4\pi(1.75)^{2}). [ \begin{align*} A&=4\pi\times3.0625\ &=12.25\pi\ &\approx12.25\times 3.14\ & = 38.465 \end{align*} ]

Answer:

The surface area of the onion can best be modeled by a sphere. Based on the model, the approximate surface area of the onion is (38.465) square inches.
