Question

How can the surface area of the onion be approximated?The surface area of the onion can best be modeled by a . Based on the model, the approximate surface area of the onion is square inches.

Answer 1

Answer:

$\text{ SA=38.5 square inches}$

Step-by-step explanation:

As we can see the onion seems like a sphere, therefore we can use the equation for the surface area of a sphere, which is represented by the following equation;

$SA=4\pi *r^2$

estimating the radio of the onion, r=1.75. The estimated surface area would be:

$\begin{gathered} \text{ SA=4\lparen3.14\rparen}*1.75^2 \\ \text{ SA=38.5 square inches} \end{gathered}$
