Answer:

Step-by-step explanation:
Given
Shape: Sphere

Required
Determine the radius (r)
A sphere's surface area of is calculated using:

Substitute value for Surface Area

Convert fraction to improper number

Divide both sides by 4



Divide both sides by


Take
as

So, we have:



Take the square root of both sides

--- approximated
Hence, the radius of the sphere is 7/6 units
