What is the surface area of a sphere with a radius of 3 centimeters?

Answers

Answer 1

Answer: The equation for the surface area of a sphere is $A=4 \pi r^(2)$

So plug in 3 cm for radius "r"

$A=4 \pi ( 3cm)^(2)$

Simplify
$A=4 \pi (9 cm^(2))$
$A=36 \pi cm^(2)$

Depending on your teacher, they might want you to leave it like this or plug in 3.14 for $\pi$
So your answer is either
$A=36 \pi cm^(2)$
or
$A=113.04 cm^(2)$

Which phrase accurately describes a distribution that's bell-shaped but not symmetric?

Answers

A skewed distribution should be the right answer. It is a distribution that's bell-shaped but not symmetric. A skewed distribution do not have a symmetric appearance unlike a normal distribution. Skewness is the measure of the asymmetry.

Answer:

The answer is skewed distribution.

Step-by-step explanation:

Which phrase accurately describes a distribution that's bell-shaped but not symmetric?

Skewness is defined as asymmetry in a statistical distribution where the curve appears distorted or skewed either to the left or to the right, but not in the center.

When distributions possess a bell shape but is not centered, then they are called skewed distributions.

Solve for r

v = 4/3 r^3

Answers

Answer:

$r=\sqrt[3]{(3v)/(4) }$

Step-by-step explanation:

To solve for $r$ :

$v=(4)/(3)r^(3)$ (given)

$(3v)/(4)=r^(3)$ (times $(3)/(4)$ on both sides)

$r=\sqrt[3]{(3v)/(4) }$

I hope this helps :)

How do you solve 4(6x-1)=120 if you're solving for x

Answers

4(6x-1)=120
Multiply the number outside the parenthesis(4) with the numbers inside the parenthesis(6 and -1)
24x-4=120
Add 4 to both sides
24x=124
Divide both sides by 24
Final Answer: x= 5.1667 or 5 1667/10,000

Round off 24.67 to one significant

Answers

Answer:

The answer is: 20

Step-by-step explanation:

Significant figures are the meaningful digits that contribute to the precision and accuracy of the given number.

The given number: 24.67 has four significant figures because all the non-zero digits are significant.

Rounding off refers to the method of expressing the given number to the nearest whole number or nearest thousand, hundred, ten, etc.

Now, rounding off the given number (24.67) to one significant figure gives 20, which has only one significant figure. As the trailing zero is not significant.

24.67 rounded to one significant figure would be 25.
