Answer: $159.2\ cm^3$

Step-by-step explanation:

The volume of cone is given by :-

$\text{Volume}=\frac{1}{3}\pi r^2h$

Given: The diameter of paper cups = 8 cm

Thus, the radius of paper cup (r)= $\frac{8}{2}=4\ cm$

The height of paper cup (h)= 9.5 cm

Now, the volume of paper cup will be :-

$\text{Volume}=\frac{1}{3}\pi (4)^2(9.5)\\\\\Rightarrow\text{Volume}=\frac{1}{3}(3.14159265359)\times(16)(9.5)=159.174027782\approx159.3\ cm^3$

Hence, the best approximation for the volume of the paper cup $159.2\ cm^3$

Carmen is simplifying the expression (6. 21 0. 93) 0. 7. She recognizes that 0. 93 and 0. 07 will combine to equal 1, so she wou

Stells [14]

To solve the problem w must know about the Associative property.

<h2>Associative property</h2>

The associative property states that the addition of the sum of two numbers (a,b) and a third number(c) is equal to the addition of the sun of the last two numbers(b, c) and the first number(a).

A+(B+C) = (A+B)+C

The property that will allow Carmen to do this without changing the value of the expression is the Associative property.

<h2>Explanation</h2>

Given to us

(6.21 + 0.93 ) + 0.07

<h3>Associative property.</h3>

Now, using Associative property,

(6.21 + 0.93 ) + 0.07

= 6.21 + (0.93 + 0.07)

=6.21 + (0.93 + 0.07)

Hence, the property that will allow Carmen to do this without changing the value of the expression is the Associative property.

Find the sum: 4 radical 3 + 11 radical 12

Ksenya-84 [330]

Answer:

$26\sqrt{3}$

Step-by-step explanation:

We want to find $4\sqrt{3} +11\sqrt{12}$ . $11\sqrt{12}$ can be written as $11\sqrt{4*3}=11*\sqrt{4} *\sqrt{3}=11*2*\sqrt{3}=22\sqrt{3}$ , so we can now write our original equation as: $4\sqrt{3}+22\sqrt{3}$ .
