Answer:
26π, 130π, 780π (inches)
Step-by-step explanation:
We first need to find how long the circumference of the circle is, since that is the part of a wheel that determines how far it will go. The formula to find the circumference is 2πr, where r is the radius. This formula is just something you have to remember, there is no way around it.
Now, applying the formula, we find that the diameter of the circle is 26π inches, which means that the bike will go 26π inches every rotation of the wheel.
To find the distance for 5 rotations, we multiply 26π by 5, getting 130π
Similarly, with 30 rotations, we get 26π*30=780π
Answer:
6.784 × 10¹⁰
Step-by-step explanation:
→ First count the number of 0's
0000000 = 7 zero's
→ Count how many decimal places until a single digit
6.784 = 3 decimal places
→ Add the number of zero's with the decimal place's
7 + 3 = 10
6.784 × 10¹⁰
Answer:
50 miles per hour
Step-by-step explanation:
To find rate, we use the rate formula:
r = rate, d = distance and t = time
Plug in distance and time using the numbers provided:
now to find rate we only need to divide 130 by 2.6 to get r = 50.
