Answer:
45.82 square inches
Step-by-step explanation:
Use the formula for the surface area of a sphere, A = 4[tex]\pi[/tex]r²
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.
