Asphere has a surface area of 60 square feet. which choice is the best approximation of its radius? use 3.14 to approximate pi.

Radius is 2.18

Step-by-step explanation:

We  have been given the surface area of sphere 60 square feet

And formula for area of sphere is

using

On substituting the values we get:

On simplification we get:

We use the following trigonometric identity to answer the question:
 sin^ 2 (theta) + cos^ 2 (theta) = 1
 We substitute the values:
 sin ^ 2 (theta) + 0.73 = 1
 We cleared:
 sin ^ 2 (theta) = 1-0.73
 sin ^ 2 (theta) = 0.27
 
 a possible value of sin ^ 2 (theta) is:
