A circle has a radius of 5.4 m. what is the exact length of an arc formed by a central angle measuring 60°? enter your answer in the box. express your answer using π .
Assuming the radius is 5.4m. The exact length of an arc formed by a central angle measuring 60° is 1.8π or 5.65.
Length of an arcArc length of the circle=(theta)/360×pi×diameter
Diameter=2×radius
Where:
radius=5.4
Diameter=2×5.4=10.8
theta=60°
Arc length:
Arc length=60°/360°×π×10.8
Arc length=5.6548667765 or 1.8π
Inconclusion the exact length of an arc formed by a central angle measuring 60° is 1.8π or 5.65.

Rebello's preferred stock pays a dividend of $1.00 per quarter, and it sells for $55.00 per share. what is its effective annual (not nominal) rate of return?
Assuming it sells for $55.00 per share. Its effective annual (not nominal) rate of return is 7.47%.
Effective annual rate of returnUsing this formula
Effective annual rate of return=[1+(Preferred quarterly dividend+Preferred stock price]^Periods per year-1
Where:
Periods per year =4
Preferred quarterly dividend=$1.00
Preferred stock price=$55.00
Let plug in the formula
Effective annual rate of return = [1+ ($1.00/$55.00)]^4 - 1
Effective annual rate of return=(1+0.018181818)^4-1
Effective annual rate of return=(1.018181818)^4-1
Effective annual rate of return =1.0747-1
Effective annual rate of return =0.0747×100
Effective annual rate of return = 7.47%

Find the amount applied to principle for the third month of a 4-year loan of $ which charges percent compounded monthly with monthly payments.
The amount applied to the principal for the third month of a 4-year loan of $50,000 at an interest rate of 10% per year with monthly payments is $865.71.
What is the amount of payment applied to the principal?The amount of the payment applied to the principal in any payment period is the total payment less the interest amount for the payment period.
For example, in this case, the periodic payment is $1,268.13. However, the interest amount for the month is $402.42 ($48,289.98 x 10% x 1/12).
The amount of the payment applied to the principal is $865.71 ($1,268.13 - $402.42).
This can be computed using an online finance calculator that calculates the periodic payment and prepares a monthly payment schedule as below.
Data and Calculations:N (# of periods) = 48 (4 x 12)
I/Y (Interest per year) = 10%
PV (Present Value) = $50,000
FV (Future Value) = $0
Results:
PMT = $1,268.13
Sum of all periodic payments = $60,870.20
Total Interest = $10,870.20
Monthly Schedule
Period PV PMT Interest Principal FV
1 $50,000.00 $1,268.13 $416.67 $851.46 $49,148.54
2 $49,148.54 $1,268.13 $409.57 $858.56 48,289.98
3 $48,289.98 $1,268.13 $402.42 $865.71 $47,424.27
