Now to solve this problem, all we have to remember is the
formula for calculating the linear speed given the radial speed, that is:
v = r w
where,
v = is the linear velocity or linear speed
r = is the radius of the circular disk = (1 / 2) diameter
= (1/ 2) (2.5 inches) = 1.25 inches
w = is the radial velocity (must be in rad per time) =
7200 rev per minute
Calculating for v:
v = 1.25 inches (7200 rev per minute) (2 π rad / 1 rev)
v = 56,548.67 inches / minute
Converting to miles per hour:
v = 56,548.67 inches / minute (1 mile / 63360 inches) (60
min / hour)
<span>v = 53.55 mile / hour</span>
Percent error=100*(measurement-actual dimension)/actual dimension
pe=100(5.12-6)/6=-14.67%
So there is a 14.67% error.

Answer:
- repeating
- repeating
- repeating
- non-repeating
Step-by-step explanation:
There are two ways that repeating decimals are indicated. One of them is putting an overbar over the digits that repeat. The other is to show the repeat of digits, followed by an ellipsis (...).
