Answer:
D
Step-by-step explanation:
We need the formula for arc length (in radians) to solve this problem. The formula is:
Where
s is the arc length
r is the radius of the circle
is the intercepted angle
In this diagram, we can see that is beign intercepted by the big arc with measure 20 cm. So arc length, s, is 20
Also, if we look, we see that the radius is 5 cm, so r = 5
Now, we substitute into formula and find :
This is given in radians, so is 4 radians
D is the correct answer choice.

Answer:
the actual hourly percent increase is 6.823 %
Step-by-step explanation:
Given that data in the question;
rate chemical decomposes increasing continuously at 6.6 %,
r = 6.6% = 0.066
actual hourly percent increase = ?
Now,
hourly percent increase = ( - 1 ) × 100%
we substitute
hourly percent increase = ( - 1 ) × 100%
hourly percent increase = ( 1.06823 - 1 ) × 100%
hourly percent increase = 0.06823 × 100%
hourly percent increase = 6.823 %
Therefore, the actual hourly percent increase is 6.823 %
