From the calculation done below, the interest when the rate is 9% is $101.25.
<h3>How interest is calculated using direct variation?</h3>
Since the interest on investment varies directly as the rate of interest, the relevant direct variation formula to use to calculate investment is as follows:
i = kr ................................. (1)
Where:
i = interest amount = $45
k = investment = ?
r = interest rate = 0.04
Substituting the values into equation (1) and solving for k, we have:
45 = k0.04
k = 45 / 0.04
k = $1,125
To find the interest when the rate is 9%, we substitute k = $1,125 and r = 9% into equation (1) as follows:
i = $1,125 * 9% = $101.25

Answer:
C.
Step-by-step explanation:
Since the radius of the circle is 12 units, we can calculate the circumference.
2 * pi * r = 2 * pi * 12 = 24 * pi = 24pi.
The arc angle is 240 degrees, and the whole circle would be 360 degrees. So, we can set up an equation.
1 * x = 4 * 4 * pi
x = 16pi
So, your answer is C.
Hope this helps!
