The summand (R?) is missing, but we can always come up with another one.
Divide the interval [0, 1] into subintervals of equal length

Let's consider a left-endpoint sum, so that we take values of where
is given by the sequence
with . Then the definite integral is equal to the Riemann sum
Write 720,080 in expanded form with exponents
First we the place chart for numbers and exponents as well
HTh TTh Th H Tens ones
7 2 0 0 8 0
10^5 10^4 10^3 10^2 10^1 1
Now we write the expanded form with exponents
0 times anything is 0
So expanded form is
Assuming the clock to be round in shape, we can treat the minute hand length as the radius of the circle.
We want to know the length, in inches, of 4 full rotations.
1 full rotation length is the circumference of the circle with radius 5 <u>(minute hand is radius and has length 5 inches)</u>. We use the formula of the circumference of a circle to get length in 1 rotation:
So for 4 full rotations, the length covered is inches.
Rounding to nearest tenth of an inch, we have:
inches
ANSWER: or 125.7 inches
