Answer:

6cm

Step-by-step explanation:

$A = \frac{h_b b}{2}$

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

Step-by-step explanation:

<u>Step 1: Define</u>

SA = 23 in²

<u>Step 2: Find </u><em><u>r</u></em>

Substitute [SAS]: 23 in² = 4πr²
Isolate <em>r </em>term: 23 in²/(4π) = r²
Isolate <em>r</em>: √[23 in²/(4π)] = r
Rewrite: r = √[23 in²/(4π)]
Evaluate: r = 1.35288 in

<u>Step 3: Find </u><em><u>d</u></em>

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