Answer:

D. 2.19

Step-by-step explanation:

ok so the formula for the surface area of a sphere is 4[tex]\pi[/tex][tex]r^2[/tex]

We see that 4[tex]\pi[/tex][tex]r^2[/tex]=60.

To find the radius we must isolate r on one side of the equations.

[tex]r^2[/tex]=60/4[tex]\pi[/tex]

[tex]r^2[/tex] = 4.77464829276

r = [tex]\sqrt{4.77464829276}[/tex]

That is approximately equal to 2.19
