Answer:
15.71 ft
Step-by-step explanation:
Given that:
width of the circular track = 2.5ft
Suppose the radius of the inner circle is 57 ft since it is not given
Then the radius of the outer circle = (2.5 + 57) ft = 59.5 ft
The circumference of a circle = 2πr
For inner circle now, the circumference = 2 × π × 57 ft
For inner circle now, the circumference = 358.14 ft
For the outer circle, the circumference = 2 × π × 59.5 ft
For the outer circle, the circumference = 373.85 ft
The difference between the circumference of the outer wheel from the inner wheel shows how farther does a wheel on the outer rail travel than a wheel on the inner rail of the track in one turn
∴
= ( 373.85 - 358.14 ) ft
= 15.71 ft
6 - n if you're doing equations
The number can be positive or negative. If the number (n) is negative, the answer will come out positive, because - and - = +
If the number (n) is a positive, and above 7, the answer will be a negative.
X to the second power equals 14 is the same as:
we can take the square root of both sides to get:
because we cannot simplify the 14 inside the square root symbol, our final answer is
There are 15 sixteenths in 15/16.
