1/3 of 39,900 equals 1/3*39900

(1/3)*(39900/1)= 39900/3

39900/3= 13300

Final answer: 13,300

Two spheres have volumes of 8,cm and 647 cmIf the surface area of the smaller sphere is 16 cm?, what is the surface

Olegator [25]

Answer:

361.7cm²

Step-by-step explanation:

Volume of sphere 1= 8cm³

Volume of sphere 2 = 647cm³

But volume of sphere = 4/3πr³

The radius of sphere 2

647 = 4/3πr³

((3*647)/4)/π= r³

5.36544 = r

Surface area = 4πr²

Surface area for the big sphere

= 4π5.36544²

= 361.7cm²

Th The Future Businesses leaders of America club is setting up a school store. Members plan to sell pens and pencils. A pen is $

coldgirl [10]

Step-by-step explanation:

<u>Prices:</u>

$C_{pen}=1.25$

$C_{pencil}=0.25$

Goal:

$n_{pen}=50$

$n_{pencil}=100$

$E=115$

Earnings for 50 pens and 100 pencils

$E=50*1.25+100*0.25=87.5$

As can be seen, they have to either rise the number of pens and pencils they would like to sell, or they will have to lower they goal of learning

The volume of a cylinder is 1087 cm and its height is 12 cm.

Ierofanga [76]

Step-by-step explanation:

<h3>Appropriate QuestioN :</h3>

The volume of a cylinder is 108π cm³ and its height is 12 cm. What is the length of the cylinder's radius?

We have to find the length of the cylinder's radius.

$\red{\frak{Given}} \begin{cases} & \sf{Volume\ of\ the\ cylinder\ =\ {\pmb{\sf{108{\pi}\ cm^3.}}}} \\ & \sf{Height\ of\ the\ cylinder\ =\ {\pmb{\sf{12\ cm.}}}} \end{cases}$

We know that,

The volume of a cylinder is the density of the cylinder which shows the amount of material contained in the cylinder.
The volume of the cylinder is given by, πr²h.

Where,

r is for radius.
h is for height.

$\rule{200}{3}$

Now, let's calculate the length of the cylinder's radius.

$\sf \dashrightarrow {Volume\ of\ cylinder\ =\ {\pi}r^2h} \\ \\ \\ \sf \dashrightarrow {108{\pi}\ =\ {\pi}r^2h} \\ \\ \\ \sf \dashrightarrow {108{\cancel \pi}\ =\ {\cancel \pi}r^2 \times 12} \\ \\ \\ \sf \dashrightarrow {108\ =\ r^2 \times 12} \\ \\ \\ \sf \dashrightarrow {\dfrac{\cancel{108}}{\cancel{12}}\ =\ r^2} \\ \\ \\ \sf \dashrightarrow {r^2\ =\ 9} \\ \\ \\ \sf \dashrightarrow {r\ =\ \sqrt{9}} \\ \\ \\ \dashrightarrow {\underbrace{\boxed{\pink{\frak{r\ =\ 3\ cm.}}}}_{\sf \blue{\tiny{Radius\ of\ cylinder}}}}$

∴ Hence, the length of the cylinder's radius is 3 cm.
