Question

Rearrange the formula V = 2πr/T

for r.

A)r = π/2TV

B)r = 2π/TV

C)r = 2TV/π

D)r = TV/2π

Answer 1

The answer I got was d.

Answer 2

Answer: D.
`(Tv)/(2\pi)`

Explanation:

The given formula :
`V=(2\pi r)/(T)`

To rearrange the given formula in terms of r, first we need to multiply T on the both sides, we get

`VT=2\pi r`

In the second step, divide
`2\pi` on both the sides, we get

`r=(VT)/(2\pi)`

Hence , the rearrange formula for r =
`(VT)/(2\pi)`
