if you are given diameter ,then radius=diameter/2

if you are given the co-ordinates of extremities of diameter then find diameter by distance formula and then radius as given above.

if area is given the area=πr²

r=√(area/π)

if circumference C is given then C=2πr

r=C/2π

<h2>Answer:</h2>

$\frac{1}{64}$

<h2>Step-by-step explanation:</h2>

$The\ probability\ of\ tails\ per\ flip\ is\ \frac{1}{2}$

$so\ the\ probability\ of\ getting\ six$

$tails\ is$

$\frac{1}{2}\times\frac{1}{2}\times\frac{1}{2}\times\frac{1}{2}\times\frac{1}{2}\times\frac{1}{2}=\frac{1}{64}$

$The\ probability\ of\ getting\ tails\ every$

$time\ you\ multiply\ them\ is\ the$

$probobility\ of\ getting\ tails\ all\ six$

$times?$

Answer:

W(t) = 10 + 1.5*t

Step-by-step explanation:

Given:

The weight gain of the baby is 1.5 pounds per month.

After 4 months, baby's weight = 16 pounds

Let us the say the weight of the baby when it was born be x.

Then:

x + 1.5*(4) = 16

x = 10

Then weight of the baby as a function of number of months(t) will be=

initial weight + incremental weight per month*no of months(t).

W(t) = 10 + 1.5*t
