Question

please help answer both questions

Answer 1

Answer:

1. $503.08

2. 5071

Step-by-step 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

Answer 2

Step-by-step explanation:

Step 1:  Answer the first question

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

$P = (3.14 * \frac{27}{2}) + 27$

$P = 42.39 + 27$

$P = 69.39$

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
