Answer:
90$
Step-by-step explanation:
(12 pairs of jeans * $7.50) / 1 pair of jeans = 90$
It would decrease because you are multiplying by a decimal.
Circumference = 2 · π · r or π · d
Radius = 7.8
7.8 × 2 = 15.6
15.6 × 3.14(π) = 48.984
Circumference = 48.984 rounded = 49
Area = π · r²
Radius = 7.8
7.8 × 7.8 = 60.84
60.84 × 3.14(π) = 191.0376
Area = 191.0376 rounded = 191
