There are 360° in a full circle. Our given arc subtends an angle of 30°, and since 360 = 30 x 12, we can also multiply the length of the arc by 12 to find that our circumference is 8 x 12 = 96.

theta = arc/radius, theta being in radian, so theta = pie / 6, radius = arc / theta = 15.278 (unit if the arc) and then multiply that by 2 pie to get the circumference sorry :D, if you have a guide answer and my answer is wrong please tell me to revise

Amelia borrows $13450 for a round-the-world trip. Her repayments are $128 per week for 3 years. How much interest is she charged

ololo11 [35]

First we need to calculate the total payments by multiplying the payment per week times number of weeks in a year times 3 years
Total payments=128×52weeks×3years
=19,968

Subtract the amount borrowed from the total payments to get the interest charged
Interest charged
=19,968−13,450=6,518

Hope it helps!
