Step-by-step explanation:

<u>Step 1:  Answer the first question</u>

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

<u>Step 2:  Answer the second question</u>

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

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:

diameter = 2.5 feet

Step-by-step explanation:

Circumference of a circle is given as C = πd

Circumference of the tree trunk = 7.85 ft

π = 3.14

Diameter of the tree trunk = d

Thus:

7.85 = 3.14*d

Divide both sides by 3.14

7.85/3.14 = 3.14*d/3.14

2.5 = d

d = 2.5 ft

Someone want to help me with some Geometry?
Aleks04 [339]
The second answer that uses = is not correct, because the pentagons are similar not congruent.
The third answer is not correct, because that sign means estimated, not similar.
I've never seen the fourth sign, so by process of elimination I believe the answer is the first one.
