Sagot :

Answer:

45.82 square inches

Step-by-step explanation:

Use the formula for the surface area of a sphere, A = 4[tex]\pi[/tex]

If the diameter is 3.82 inches, the radius is 1.91 inches.

Plug in 3.14 as [tex]\pi[/tex] and 1.91 as r, and solve:

A = 4[tex]\pi[/tex]r²

A = 4(3.14)(1.91²)

A = 45.82

So, approximately 45.82 square inches of material are needed.
