sweet [91]

<span>the answer: the main condition can be found one of the following given methods: if A = B*C*D, if we want to find the value of B, so B = A /C*D, the similar method can be applied to find the value of C an D. These are C= A/ B*D and D = A /C*B in our case we have C = 2*Pi* R, if we want to find the value of Pi, it is Pi = C / 2*R the true answer is D</span>
