Having the angle in radians and the diameter of the circle we can easily calculate the length using the following expression
Length = angle(radians)*diameter/2
With this expression we can easily deduce the perimeter of a circle (length of the full arc)
Length = Perimeter = 2*pi*r
There is only one operation involved in this process
According to (-b/a)
So --9/3=3
(-b/a) is the equation of the slope
There are 6 numbers on a dice 1,2,3,4,5,6. If you want to get a 4 or a 5, that would be 2 numbers out of the total number of numbers There 6 numbers in total so the probability of getting a 4 or 5 is 2 out of 6 or 1 out of 3 or 1/3
Bidmas so 43-7 then divide by 6 then add 12
