The diameter of a circle is 38 in. Find its area to the nearest whole number.

nikklg [1K]

Answer:

1134

Step-by-step explanation:

Formula for diameter=2 x r

(π is 3.14)

Formula for area= π x r^2

So all you basically have to do is go backwords with the first one then plug the radius into the second one normally

38/2=19

Now just plug it into your second equation

π x 19^2=1134.11494795

And lastly round that to 1134, easy! :)

An ancient Chinese candle clock tells the amount of time that has passed by the amount of wax that has been melted off the candl

maxonik [38]

Answer:

$Time = 560\ mins$

Step-by-step explanation:

Given

$Candles = 2$ --- candles melted

$Divisions = 12$

$Time = 4\ hrs$ --- time to melt

Required

The time since the first was lit

If 1 candle melts in 4 hours, 2 candles will melt in 8 hours.

i.e.

$x = Candles * Time$

$x = 2 * 4hrs$

$x = 8hrs$

For the 3rd candle that has melted, 4 inches

First, calculate the fraction that melt

$Fraction = \frac{Melt}{Division}$

$Fraction = \frac{4}{12}$

$Fraction = \frac{1}{3}$

The time to melt is:

$y = Fraction * Time$

$y= 4 * \frac{1}{3}$

$y= \frac{4}{3}hrs$

So, the required time is:

$Time = x + y$

$Time = 8hrs + \frac{4}{3}hrs$

Convert to minutes

$Time = 8*60mins + \frac{4}{3}*60mins$

$Time = 480mins + 80mins$

$Time = 560\ mins$

Find the missing factor 5y^2-4y-9=(y+1)

disa [49]

Answer:

y = {1,2}

Step-by-step explanation:

5y^2 - 4y - 9 = y + 1

5y^2 - 5y - 10 = 0

5(y^2 - y - 2) = 0

5 (y - 2) (y - 1) = 0

y = {1,2}

Find the measure of 0. Round answer to the nearest tenth. Pleas help

DENIUS [597]

Answer:

$\theta=36.43^{\circ}$

Step-by-step explanation:

Given that,

Base = 42

Perpendicular height = 31

We need to find the value of $\theta$ . It can be calculated using trigonometry as follows :

$\tan\theta=\dfrac{P}{B}\\\\\theta=\tan^{-1}(\dfrac{P}{B})$

Put all the values,

$\theta=\tan^{-1}(\dfrac{31}{42})\\\\\theta=36.43^{\circ}$

So, the value of $\theta=36.43^{\circ}$ .
