Answer:1,978.2
Step-by-step explanation: we will need to find the circumference (the perimeter of a circle). The formula for the circumference is C=2пr
The diameter is 2r, so we have to divide 42 by two. You get 21 for the radius. We will use 3.14 for the pi.
then you plug it in to the formula
C = 2 (3.14) * 21
The answer is 131.88
Then times that with 3
you get 395.64
but since it has been 5 minutes, then you times it with 5
that's 1,978.2
