Identify the volume and surface area of the sphere in terms of π. HELP PLEASE!!

Helen [10]

Answer:

First choice V = 18,432π m^3; S = 2,304π m^2

Step-by-step explanation:

Start with the two formulas:

Volume of a circle:

$V = \dfrac{4}{3} \pi r^3$

Surface area of a circle:

$S = 4 \pi r^2$

Now use r = 24 m in each formula.

Volume:

$V = \dfrac{4}{3} \pi (24~m)^3$

$V = \dfrac{4}{3} \pi (13,824~m^3)$

$V = 18,432\pi~m^3$

Surface area:

$S = 4 \pi r^2$

$S = 4 \pi (24~m)^2$

$S = 4 \pi (576~m^2)$

$S = 2,304\pi ~m^2$

Answer: First choice V = 18,432π m^3; S = 2,304π m^2

On a school bus, the female teacher sitting in front of me asked if I passed gas, why did she ask me that out of nowhere and whi

kobusy [5.1K]

Answer: She was buggin'

Step-by-step explanation:

If you divide <u>the fact that she's a teacher</u>

kids can smell sometimes <u> </u>

Logically you would get: maybe she thought she smelled something

But when you apply the 'mind your own business rule, it cancels out any chance of her turning around to ask you that

so you're answer is: she was buggin'

Other possible answers:

"No that's just your upper lip sis"

"Did you?"

Mary has a collection of nickels and quarters for a total value of 4.90.if she has 42 coins total how many of each kind are ther

Ray Of Light [21]

Let x be the number of nickels and y be the number of quarters.

Then, x + y = 42 --- (1)

It is given that total value = 4.90.

Therefore, 0.05x + 0.25y = 4.9 --- (2)

Multiply (1) by 0.25

0.25x + 0.25y = 10.5 --- (3)

Now, subtract (2) from (3), we get,

0.2x = 5.6

Divide both sides by 0.2.

x = 28

x + y = 42

y = 42 - x

= 42 - 28

= 14

Hence, Mary has 28 nickels and 14 quarters in total.
