1 answer:
marysya [2.9K]4 years ago
5 0

Answer:

40

Step-by-step explanation:

if you used cross products you'd pair 8 with 100 and n with 20

That written out would be 8(100)=20n

8(100)=800

800=20n

Divide on both sides

800/20=40

20/20 (cancels out)

Therefore n=40

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

Step-by-step explanation:

<u>Step 1: Define</u>

d = 19 cm

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

  1. Substitute [R]:                    r = 19 cm/2
  2. Divide:                                r = 9.5 cm
  3. Substitute [SAS]:               SA = 4π(9.5 cm)²
  4. Exponents:                        SA = 4π(90.25 cm²)
  5. Multiply:                             SA = 361π cm²
  6. Multiply:                             SA = 1134.11 cm²
  7. Round:                               SA ≈ 1134 cm²
