What is the effect on the volume of a sphere if the radius is divided by 3?

Neko [114]

For this case we have by definition, that the volume of a sphere is given by:

$V = \frac {4} {3} \pi * r ^ 3$

Where:

r: It is the radius of the sphere

If the radius is divided by 3 we have:

$\frac {r} {3}:$

$V = \frac {4} {3} \pi * (\frac {r} {3}) ^ 3\\V = \frac {4} {3} \pi * \frac {r ^ 3} {27}\\V = \frac {4} {81} \pi * r ^ 3$

ANswer:

the volume decreases considerably because the denominator increases

Find the value of x.

kirza4 [7]

Hey there :)

Here we need to use Trigonometry!

The given angle is 61°
The opposite to the angle is 22
So x is the adjacent

The trigonometric ratio that uses opposite and adjacent is tan
( I have uploaded a picture to help you )

tan α = $\frac{opposite}{adjacent}$
tan 61 = $\frac{22}{adj}$
adj = $\frac{22}{tan(61)}$
adj ≈ 12.19 ≈ 12

x = 12

B)Emily either switched the signs for no reason or solved it in the incorrect order

C) The sudent solved the equation in an incorrect order. Emily solved the first, then third, then second, which was the incorrect order. Edgar solved the thirst root, then second, then third, thus he is correct.

A grid model with 100 squares. 73 squares are shaded. What percent of the model is shaded? What is the equivalent ratio? What is

viva [34]

Answer:

73%

Step-by-step explanation:

First, you'll divide the total squares by 100 to get how much is one percent. Then, you divide the shaded squares by the value of 1%. And you'll get how many percents are shaded.

For equivalent decimal, you divide the number by 100.

Then for equivalent decimal, you get the percent and 100.

$p =100/100=1\\73/1=73\\=0.73\\=\frac{73}{100}$
