Answer:
6.25716517287
Step-by-step explanation:
Area of circle = π × r²
→ 123 = π × r²
⇒ Divide both sides by π
→ 39.1521160006 = r²
⇒ Square root both sides
→ 6.25716517287 = r

Step-by-step explanation:
1.
√2 • √3 • √3 = 4.242640687119285
3√2 = 4.242640687119285
2.
√2 • √3 • √-3 = 4.24264069i
3i√2 = 4.24264069i
3.
√-2 • √-3 • √-3 = -4.24264069i
-3√2 = -4.24264069i
4.
√2 • √-3 • √-3 = -4.24264069i
-3i√2 = -4.24264069i
(8r + 6)(4r + 10) = 32r^2 + 80r + 24r + 60 = 32r^2 + 104r + 60
