By definition of $\pi$ , we have

$\pi=\dfrac{C}{d}$

and we deduce

$d = \dfrac{C}{\pi}$

Now, recall that the diameter is twice the radius:

$2r=\dfrac{C}{\pi}$

and solve for $r$ :

$r=\dfrac{C}{2\pi}$

So, divide the circumference by $2\pi$ and you'll find the radius.

Complete the steps to solve the polynomial equation x^3 – 21x = –20. According to the rational root theorem, which number is a p

Ber [7]

X^3 - 21x = -20
add 20 to both sides
x^3 - 21 x + 20 = 0
Rational Root Theorem:
Factors of P (constant) 20 = 1, 2, 4, 5, 10, 20
-------------------------------
Factors of Q (leading Coefficient) = 1

Possible zeros (all + -) 1/1, 2/1, 4/1, 5/1, 10/1, 20/1

Of the choices given only the number 1 is a possible root.
