Answer:

The amount of paper needed = 363.3 in²

Total amount of paper and plastic needed = 564.3 in

Step-by-step explanation:

As the diagram isn't given.

Consider a right cone shown in the ATTACHMENT.

where

r = 8 in

h = 12 in

First find the value of hypotenuse s by using Pythagoras theorem

<h3>Find Lateral Area:</h3>

The amount of paper needed to cover the candle is lateral area, which is given by:

L=\pi\cdot{r}\cdot{s}\\L =\pi\cdot8\cdot14.422\\L=363.3in^2\\

<h3>Find Surface Area:</h3>

Total amount of paper and plastic is the surface area:

S=L+\pi{r}^2\\S=363.3+\pi(8)^2\\S=564.26in^2

S=564.3in^2

sarà needs three forth cup of dish soap to make homemade bubble solution. her measuring cup is divided into eighths.what fractio
Lesechka [4]
She will need 6/8 because 3/4 the cup is divided into 8 so we need the denominator to be 8. we multiply 4 x 2 and what every we do to the top happens to the bottom so we also multiply 3 x 2. then we see that sara needs 6/8 cups of dish soap to make her bubbles

In the statement, “Weight is a function of height,” which variable is the input and which is the output?
3241004551 [841]

Answer:

A. Height is input, Weight is output

Step-by-step explanation:

We are given the statement,

"Weight is a function of height".

As we know,

<em>In a function of the form y=f(x), the input variable is 'x' and the output variable is 'y'.</em>

If we write the given statement in the form y=f(x), we get,

Weight=f(Height)

This means that the input variable is 'Height' and the output variable is 'Weight'.

Hence, option A is correct.
