Answer:

the answer is 1100. my dad has a math degree and this is what he told me.

Step-by-step explanation:

he told me that the figure has 2 shapes, a square and a rectangle but how many are their. we have 4 faces of rectangles and 2 faces of squares. so the squares equal 11*8 = 88 * 2 (because of 2 squares) which will give u 176, and the rectangle which is 11 * 21 = 231 * 4 (because of 4 rectangle sides) 924. now add them 924 + 176 is 1100

What is the lateral area of the cone? 10 yd and 12.1 yd
Harman [31]

Answer:

The lateral area will be "381 yd²". A further solution is provided below.

Step-by-step explanation:

The given values are:

Radius of cone,

r = 10 yd

Height of cone,

L = 12.1 yd

As we know,

The lateral surface area of cone is:

=  \pi r L

On substituting the values, we get

=  \frac{22}{7}\times 10\times 12.1

=  \frac{22}{7}\times 121

=  380.28 \ yd^2

0r,

=  381 \ yd^2

What is the additive inverse of -2 + 8i?
tatuchka [14]

Answer:

2 - 8i

Step-by-step explanation:

The additive inverse of something is basically the opposite of it. Another way to say this is that when you add the additive inverse to -2 + 8i, it will equal 0.

<u>An example:</u>

The additive inverse of 7 is -7 because not only is it the opposite, but also when you add 7 and -7, it equals 0.

<u>To solve</u>

So all you need to do is find the opposite of -2 + 8i. You can write it as:

-(-2 + 8i)  With the negative in the front because we want to find the opposite.

This then equals:

2 - 8i

You can check your answer by adding -2 + 8i and 2 - 8i to see if it equals 0:

(-2 + 8i) + (2 - 8i)  →  and it does equal 0

<u>ANSWER:</u> 2 - 8i

Hope you understand and that this helps with your question! :)
