A circular path 3 feet wide has an inner diameter of 350 feet. How much farther is it around the outer edge of the path than aro

kobusy [5.1K]

Answer:

18.84 feet farther is it around the outer edge of the path than around the inner edge.

Step-by-step explanation:

Given:

A circular path 3 feet wide has an inner diameter of 350 feet.

Use 3.14 for π.

Now, to find how much farther is it around the outer edge of the path than around the inner edge.

Width of the circular path = 3 feet.

Inner diameter of circular path = 350 feet.

So, to get the inner radius we divide the inner diameter of circular path by width of circular path:

$350\div 3$

$=116.67\ feet.$

r = 116.67 feet.

Now,

Thus, the outer radius is:

$116.67+3$

$=119.67\ feet.$

R = 119.67 feet.

Now, we get the circumference of inner edge and outer edge:

Circumference of inner edge = 2πr.

$Circumference\ of\ inner\ edge=2\times 3.14\times 116.67$

$=732.69\ feet.$

Circumference of outer edge = 2πR.

$Circumference\ of\ outer\ edge=2\times 3.14\times 119.67$

$Circumference\ of\ outer\ edge=751.53\ feet.$

Now, to get how much farther is it around the outer edge of the path than around the inner edge:

Circumference of outer edge - circumference of inner edge.

$751.53-732.69$

$=18.84\ feet.$

Therefore, 18.84 feet farther is it around the outer edge of the path than around the inner edge.

In a scale drawing of a house, 1 inch=4 1/2 feet. If the length of a kitchen is 2 1/4 inches on a scale drawing, what is the act

ch4aika [34]

Answer:

10.125 feet.

Step-by-step explanation:

you can use the rule of three to answer this question, the data we have is:

inches feet

1 → 4 1/2

2 1/4 → x

tha last table just indicates what the problem tells us, that one inch is equal to 4 1/2 feet and we want to know how much in feet the 2 1/4 inches are.

For this we multiply the cross quantities:

$x=(2\frac{1}{4} )(4\frac{1}{2} )=2.25*4.5=10.125 ft$

the actual length of the kitchen is 10.125 feet.
