A cube has a side length of x inches. What expression represents the total volume, in cubic inches, of the cube?

Pie

Answer:

Volume = $x^3$ cubic inches

Step-by-step explanation:

A cube is the 3D version of a square. Since one side length is x inches, all the other side lengths are same, x inches each.

We know,

Volume = area of base * height

THe base is a square and the area is side * side. We know each side is x, so we have:

Area of Square = Area of Base = x * x = $x^2$

Now, we know height is also same side length, x, thus the volume becomes:

Volume = area of base * height

Volume = $x^2*x$

We add the exponents when we have same base multiplied, so the expression for volume becomes:

Volume = $x^2*x=x^3$

The radius of a circular plate is 12 centimeters. What is the area, in square centimeters, of this plate? Write your Anwer using

lesya [120]

Answer:

The area of circular plate is <u>144π square centimeters</u>.

Step-by-step explanation :

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

Here, we have given that the radius of circular plate is 12 centimeters.

So, finding the area of circular plate by substituting the values in the formula :

$\longrightarrow{\pmb{\sf{Area_{(Circle)} = \pi{r}^{2}}}}$

$\longrightarrow{\sf{Area_{(Circle)} = \pi{(12)}^{2}}}$

$\longrightarrow{\sf{Area_{(Circle)} = \pi{(12 \times 12)}}}$

$\longrightarrow{\sf{Area_{(Circle)} = \pi{(144)}}}$

$\longrightarrow{\sf{Area_{(Circle)} = \pi \times 144}}$

$\longrightarrow{\sf{Area_{(Circle)} = 144\pi}}$

$\star{\underline{\boxed{\frak{\purple{Area_{(Circle)} = 144\pi\: {cm}^{2}}}}}}$

Hence, the area of circular plate is 144π square centimeters.

Jinney wants to deduct the sales tax that she paid this year on her state income return. She paid $4960.80 during the year, incl

Sergio [31]

T = state income return (without sales tax)

106% of t = 4960.80
AKA
1.06t = 4960.80 --> Divide both sides by 1.06 to find the state income return without sales tax
t = 4680

Subtract t from the state income return with sales tax.

4960.80 - 4680 = 160.80

<u>She paid $160.80 in sales tax.</u>
