The formula for the bowline of a sphere is V=4/3πr^3. solve for r
Tpy6a [65]

Answer:

r=\sqrt[3]{\frac{3V}{4\pi}}

Step-by-step explanation:

v= \frac{4}{3} \pi r^3

We need to isolate 'r'

To isolate 'r' , first multiply by 3 on both sides

3v=4* \pi r^3

divide by 4pi on both sides

\frac{3V}{4\pi} = r^3

Take cube root on both sides

\sqrt[3]{\frac{3V}{4\pi}}= r

Find the area of this parallelogram.<br> 13 cm<br> 15cm<br> h<br> 20cm
Margaret [11]

Answer:

260 square centimeters

Step-by-step explanation:

The formula for the area of a parallelogram is:

b x h

Where the base (b) is multiplied by the height (h) perpendicular to it.

The base here is 20 cm

The height perpendicular to the base is 13 cm

20 x 13 = 260

Or you can decompose and rearrange it into a rectangle. You will get 20 cm as the length and 13 cm as the width. The answer will be just the same!

Hope this helps!
