Answer:
<u>18.84 feet</u> 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:
r = 116.67 feet.
Now,
<em>Thus, the outer radius is:</em>
R = 119.67 feet.
Now, we get the circumference of inner edge and outer edge:
Circumference of inner edge = 2πr.
Circumference of outer edge = 2πR.
Now, to get how much farther is it around the outer edge of the path than around the inner edge:
<em>Circumference of outer edge - circumference of inner edge.</em>
Therefore, 18.84 feet farther is it around the outer edge of the path than around the inner edge.
<u>Answer:</u> The value of x will be 2.
<u>Step-by-step explanation:</u>
To calculate the value of 'x' or solve for x, we need to isolate x from 8.
In the equation, 8 is in addition with 'x' so for isolating it, we need to apply the reverse operation of addition.
Reverse operation of addition is subtraction.
We need to subtract 8 from both sides of the equation, we get:
By doing this, we get the value of 'x' as 2.
Error done by Alice was that she added 8 and it did not led to the isolation of 'x'.
