The speedometer needle in a car is 2.5 inches long. When accelerating from 0 to 60 miles per hour the needle sweeps out an arc of 130°. What is the arc length traveled by the needle, in inches? Round your answer to the nearest hundredth. Use 3.14 for \piπ.

ok

step-by-step explanation:

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b
