Answer:

[tex]\text{ SA=38.5 square inches}[/tex]

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;

[tex]SA=4\pi *r^2[/tex]

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

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