Answer:

The amount of string needed is 25.1 inch.

Step-by-step explanation:

The amount of string needed to go around is equal to the circumference of that area. As the bottom of cone is to go around by string, the circumference will provide us with the right amount.

           radius (r) = 4 inch.

                      π = 3.14

circumference of circle (C) = 2πr

                                          = 2 *π *r

                                          = 2 *3.14 *4

                                          = 25.1 inch.

Hence 25.1 inch string will go around the cone easily.

Pierre throws a snowball up in the
erastovalidia [21]

Using the given function, it is found that the snowball traveled 4 feet when the height is 20 feet.

<h3>What is the function for the ball's height?</h3>

The height when x feet are traveled is given by:

h(x) = -0.5x² + 6x + 4.

When the height is of 20 meters, we have that h(x) = 20, hence:

20 = -0.5x² + 6x + 4.

0.5x² - 6x + 16 = 0

x² - 12x + 32 = 0

(x - 8)(x - 4) = 0

For the first time: x - 4 = 0 -> x = 4.

The snowball traveled 4 feet when the height is 20 feet.

10 POINTS!! HURRY FAST! FIND THE BASE AND HEIGHT BASED ON THE AREA!! FIRST CORRECT ANSWER GETS 10 POINTS
Marina CMI [18]

Answer:

height = 7.78 mm, while base = 31.11

Step-by-step explanation:

First, create the equation "4x^2=242." After doing this, solve for x. Once you do this, you will find x as 7.78. The x value is your height. To find the base, multiply height by 4.

Nemos aquarium is filled with 2400 cm of water the base of the aquarium is 20 cm long and 12 cm wide what is the height of the w
SSSSS [86.1K]

The answer to this question is 10 cm

In this question, you asked the height and given the volume of water(2400cm3), aquarium length(20cm), and aquarium width(12cm).

Then you need to divide the volume with the length and width. The equation would be:

Aquarium height= volume / length / width

Aquarium height= 2400 cm3 / 20cm / 12 cm = 10cm.

MATH HELP!!!!!!!!!!!!!!!!!!!!!!!!!!
Marina CMI [18]

Question 2. :

8^2 = 64 and 9^2 = 81, therefore the square root of 65 falls between these two values, 8 and 9, 64<65<81

Question 3. :

13^2 = 169 and 14^2 = 196, the correct answer is square root of 175, because 169<175<196

Hope this helps, you only need to know the squared values and square roots.
