Answer 1

`\begin{gathered} In\text{ fraction: }x\text{ =}(4\pi rad)/(3) \\ In\text{ decimal: x = 4.1867} \end{gathered}`Step-by-step explanation:

Conversion from degrees to radians:

1 π rad = 180 degrees

if degree is 240,

let x = amount in rad

180 degrees = 1 π rad

240 degrees = x

cross multiply:

x(180) = 240(1 π rad )

180x = 240π rad

divide both sides by 180:

180x/180 = 240π rad/180

`\begin{gathered} x=(240\pi rad)/(180) \\ x\text{ =}(4\pi rad)/(3) \end{gathered}`

In decimal:

`\begin{gathered} x\text{ =}(4\pi rad)/(3),\text{ if }\pi=\text{ 3.14} \\ x\text{ = }4.1867 \end{gathered}`
