Geometry

• Surface Area of a Sphere: SA = 4πr²
• Diameter: d = 2r

Step-by-step explanation:

Step 1: Define

SA = 23 in²

Step 2: Find r

1. Substitute [SAS]:                    23 in² = 4πr²
2. Isolate r term:                         23 in²/(4π) = r²
3. Isolate r:                                  √[23 in²/(4π)] = r
4. Rewrite:                                   r = √[23 in²/(4π)]
5. Evaluate:                                 r = 1.35288 in

Step 3: Find d

1. Substitute [D]:                    d = 2(1.35288 in)
2. Multiply:                              d = 2.70576 in
3. Round:                                d ≈ 3 in
