Answer:

2.5 feet

Step-by-step explanation:

Circunference= $C = \pi d$

15.7 = 3.14 · $d$

$\frac{15.7}{3.14}$ = $d$

5 = $d$

And,

$d = 2r$

So,

$5 = 2r$

$\frac{5}{2}$ = r

2.5 = r

The height, h metres, of a particle at time, t seconds is given by the function:

vfiekz [6]

Answer:

It depends on what you are asked to do. See explanation.

Step-by-step explanation:

The height, h metres, of a particle at time, t seconds is given by the function:

h=(14-t)(t-2).

This means that after a given time, we can use this function to find the height of the particle.

For instance after 3 seconds, the height of the particle will be:

$h=(14-3)(3-2)$

This implies that:

$h=11*1=11m$

So after 3 seconds the height of the particle is 11 meters.
