The circle with center o has a minor arc bsa with a length of 3π2 inches. the central angle is 40°. what is the circumference of the circle? a) 7π2 inches b) 9π2 inches c) 13π2 inches d) 27π2 inchesthe answer is d

D. inches.

Step-by-step explanation:

We have been given that the circle with center O has a minor arc BSA with a length of inches. The central angle is 40°.

To find the circumference of circle we will use formula:

, where = measure of 360 degrees in radians and = circumference of circle.  

Let us convert measure of central angle into radians.                        

Upon substituting our given value in the formula we will get,        

Cross multiplying we will get,      

Hence, the radius of our circle is 27/4 inches.  

Since the circumference of circle is . Upon substituting   we will get,

Therefore, circumference of our given circle will be inches and option D is the correct choice.

dude thats to long figure it

step-by-step explanation:

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.
