In order to solve the formula

C=\pi d

in terms of d, you simply have to divide both sides by pi:

d=\dfrac{C}{\pi}

The total height of the earring is the sum of the diameters of the circles. Given their circumferences, the diameters are

d_1=\dfrac{6}{\pi},\quad d_2=\dfrac{8}{\pi}

So, the total height is

h=d_1+d_2=\dfrac{6}{\pi}+\dfrac{8}{\pi}=\dfrac{14}{\pi}

I am in need of some help :(It looks so simple yet I don't get how to do it. Can anyone help explain?(picture of question attach
Firdavs [7]

x = 14

Explanation:

height = x

base 1 = 98

base 2 = 2

Using altitude formula in geometric mean:

base 1/height = height/base 2

98/x = x/2

\begin{gathered} \frac{98}{x}=\frac{x}{2} \\ \text{cross multiply:} \\ 2(98)\text{ = x}\times x \end{gathered}\begin{gathered} 196=x^2 \\ \text{square root both sides:} \\ \sqrt[]{196}\text{ = }\sqrt[]{x^2} \\ x\text{ = }\sqrt[]{196} \\ x\text{ = 14} \end{gathered}
