a container of candy is shaped like a cylinder and has a volume of 125.6 cubic centimeters. If the heights of the container is 1

Elenna [48]

The radius of the container is 2 centimeter

<h3><u>Solution:</u></h3>

Given that a container of candy is shaped like a cylinder

Given that volume = 125.6 cubic centimeters

Height of conatiner = 10 centimeter

To find: radius of the container

We can use volume of cylinder formula and obatin the radius value

<em><u>The volume of cylinder is given as:</u></em>

$\text {volume of cylinder }=\pi r^{2} h$

Where "r" is the radius of cylinder

"h" is the height of cylinder and $\pi$ is constant has value 3.14

Substituting the values in formula, we get

$\begin{array}{l}{125.6=3.14 \times r^{2} \times 10} \\\\ {r^{2}=\frac{125.6}{31.4}} \\\\ {r^{2}=4}\end{array}$

Taking square root on both sides,

$r = \sqrt{4}\\\\r = 2$

Thus the radius of the container is 2 centimeter

State the property.<br>4(2+3)=(2+3)4

Komok [63]

Hmm, it looks like it could be commutative property of multiplication.

The order of the expression is different.

4(2+3)=

4(5)=20

(2+3)4=

(5)4= 20

after a birthday party, 1 4 of a large cake was left. If this piece of cake was shared equally among the 6 people, what fraction

il63 [147K]

The 6 people each got $\frac{1}{24}$ . To get this answer you need to divide the $\frac{1}{4}$ of the cake among 6 people.

Equation ⇒ $\frac{1}{4}$ x $\frac{1}{6}$

You get the answer by multiplying the bottom denominators.

twice the difference of a number and 7 is equal to three times the sum of the number and 7. find the number

otez555 [7]

Answer:

- 35

Step-by-step explanation:

2(x - 7) = 3(x+7)

2x - 14 = 3x + 21

- 21 - 14 = 3x - 2x

x = - 35

Rechecking :

2(-35 - 7) = 3 (-35 +7)

- 84 = - 84

I hope im right!!!
