Answer:

1. $503.08

2. 5071

Explanation:

1. Perimeter = (pi × r) + d

= (3.14 × 27/2) + 27

= 69.39

Cost: 69.39 × 7.25 = $503.0775

2. 17 × (pi × d)

17 × 3.14 × 95

5071.1 feet

Explanation:

Step 1: Answer the first question

Find the perimeter:
P = (\pi *r)+d But... let π be 3.14


P = (3.14 * (27)/(2)) + 27


P = 42.39 + 27


P = 69.39

Find the price: $7.25 per foot


7.25 * 69.39


\
503.0775

Answer:
\
503.0775

Step 2: Answer the second question

Find the amount traveled:
P = revolutions*\pi *d But... let π be 3.14


P = 17 * 3.14 * 95


P = 53.38 * 95


P = 5071.1

Answer: 5071.1 feet
