The length of an arc is a portion of the circumference of the circle, and the circumference itself can be considered as a full arc length. The arc length is usually represented by letter 's'. To get the arc length, we must get the proportion of the arc measure and arc length.

Arc measure = Arc length
360º Circumference

Cross multiply and transpose to get the arc length's formula. Since arc measure is equal to the central angle that intercepts the arc, we can replace arc measure to central angle.

Letter D - central angle over 360

Arc length = Central angle x Circumference
360º

Answer from: milagrosee12

The arc length by definition is given by:
s = r * theta
Where,
r: radius of the circle
theta: central angle in degrees
Substituting values we have:
s = 2πr * (theta / 360)

D. central angle over 360

$655.61 which is option c

step-by-step explanation:

price of house = $146,000

initial rate = 3.5%

mortgaged paid in this = 3.5 % of $146,000

= $\frac{3.5*146000}{100}$

=$5110

the total years would be = 7

total mortgaged paid = 7 * $5110

=$35770

remaining money = $146000-35770

=$110230

new mortgaged payment = 5 % of 110230

= $\frac{5*110230}{100}$

=$655.61
