Answer:
[tex]r=1 in[/tex]
Step-by-step explanation:
Given: The surface area of a sphere is [tex]12.56 in^2[/tex].
To find: The radius of the sphere.
Solution: It is given that the surface area of a sphere is [tex]12.56 in^2[/tex], thus we have
[tex]S.A=4{\pi}r^2[/tex] where r is the radius of the sphere.
⇒[tex]12.56=4(3.14)(r)[/tex]
⇒[tex]12.56=12.56r[/tex]
⇒[tex]\frac{12.56}{12.56}=r[/tex]
⇒[tex]r=1 in[/tex]
Therefore, the radius of the sphere is 1 inches.
