Fiona races BMX around a circular dirt course. If the radius of the course is 70 meters, what is the total distance Fiona covers in two laps of the race?

 The total distance Fiona covers in two laps of the race = 880 meters

Step-by-step explanation:

Given : Fiona races BMX around a circular dirt course.

The radius of the course is 70 meters.

Then , Circumference  of circular dirt course =

=      

Now , the total distance Fiona covers in two laps of the race = 2 x (Circumference  of circular dirt course)

= 2 x (440 meters)

= 880 meters

Hence, the total distance Fiona covers in two laps of the race = 880 meters

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

answer: no, but if it does it's a obvious pattern.
