- 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

Answer: 0.1 OR 1/10
Step-by-step explanation:
Think about it: There's 1/2 bag of oranges, and you wanna know what number of oranges used in the juice. Take 1/2, and divided it by 5. You get 0.1, then you should turn it into a fraction, giving you 1/10.
