What is the arc length when the central angle measures 60 degrees and the radius is 15 inches giving in terms of 3.14

To solve this problem, we make use of the formula for arc length:

s = r θ

where the variables are,

s = the length of the arc = unknown value

r = radius of the circle = 15 inches

θ = the angle in radians = 60 degrees

Since the given angle is in units of degrees, therefore we need to convert this first into rad:

θ = 60° (π / 180°)

θ = π / 3

Going back to the arc length formula:

s = 15 inches (π / 3)

s = 5 π inches

5 π inches

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.

step-by-step explanation :

we know that

the measurement of the outer angle is the semi-difference of the arcs which comprises

in this problem

m< xzy is the outer angle

substitute the values

the measure of angle xoy is equal to

> by central angle

substitute the value
