Find the radius of a sphere with a surface area of 1024π square inches
agasfer [191]

Answer:

<h2>R = 16 in</h2>

Step-by-step explanation:

The formula of a Surface Area of a sphere:

S.A.=4\pi R^2

R - radius

We have

S.A.=1024\pi\ in^2

Substitute:

4\pi R^2=1024\pi               <em>divide both sides by π</em>

4R^2=1024             <em>divide both sides by 4</em>

R^2=256\to R=\sqrt{256}\\\\R=16\ in

Can someone help me D: thanks in advance :D
max2010maxim [7]

Answer:

3) 27 cubed

4) 72 cubed

5) 125 cubed

8) 27 cubed. 3 is the length, 3 is the width, and 3 is the height.

9) 72 cubed. 6 is the length, 3 is the width, and 4 is the height.

10) 125 cubed. 5 is the length, 5 is the width, and 5 is the height.

Step-by-step explanation

Here's what to show if your teacher requires for you to show your work.

3) 3 x 3 x 3 = 27

4) 6 x 3 x 4 = 72

5) 5 x 5 x 5 = 125

8) 3 x 3 x 3 = 27

9) 6 x 3 x 4 = 72

10) 5 x 5 x 5 = 125

These are the ones I'd suggest putting the up and down form on.

10) and 5) Also put 5 x 5 = 25.          4) and 9) Also put 6 x 3 = 18.

     <em>2                                                        3</em>

     25                                                      18

  <u>x  5 </u>                                                     <u>x 4  </u>

   125                                                      72

Hoped this answered everything! Feel free to ask me if there's something I missed! :)
