Katena32 [7]

Answer: the diameter of the can is 2.8 inches

Step-by-step explanation:

The formula for determining the volume of a cylinder is expressed as

Volume = πr²h

Where

r represents the radius of the cylinder.

h represents the height of the cylinder.

π is a constant whose value is 3.14

From the information given,

height = 4.5 inches

Volume of can = 454 millilitres

1 cubic inch = 16.387 millilitres

Converting 454 millilitres to cubic inches, it becomes

454/16.387 = 27.7 cubic inches

Therefore

27.7 = 3.14 × r² × 4.5

27.7 = 14.13r²

r² = 27.7/14.13

r² = 1.96

r = √1.96

r = 1.4

Diameter = 2 × radius

Diameter = 2 × 1.4 = 2.8 inches

Calculate the volume of the following figure.

Leni [432]

Answer:

$\boxed{\sf{24\ units\ ^3}}$

Step-by-step explanation:

In order to solve this, you must use the volume of the cube.

$\underline{\textbf{VOLUME OF THE CUBE FORMULA:}}$

$\Longrightarrow: \sf{V=L*W*H}$

L: (length) = 3
W: (width) = 2
H: (height) = 4

Multiply.

Use the order of operations.

PEMDAS stands for:

Parentheses
Exponents
Multiply
Divide
Add
Subtract

$\Longrightarrow: \sf{3*2*4}$

First, do multiply.

$\Rightarrow: \sf{3*2=6}\\\\\\\Rightarrow: \sf{6*4=\boxed{\sf{24}}$

Therefore, the volume of the cube is 24 units³, which is our answer.

I hope this helps. Let me know if you have any questions.
