The diameter of a circle is 38 in. Find its area to the nearest whole number.
nikklg [1K]

Answer:

1134

Step-by-step explanation:

Formula for diameter=2 x r

(π is 3.14)

Formula for area= π x r^2

So all you basically have to do is go backwords with the first one then plug the radius into the second one normally

38/2=19

Now just plug it into your second equation

π x 19^2=1134.11494795

And lastly round that to 1134, easy! :)

Solve for r<br><br>v = 4/3 r^3<br>​
sergejj [24]

Answer:

r=\sqrt[3]{\frac{3v}{4} }

Step-by-step explanation:

To solve for r:

v=\frac{4}{3}r^{3} (given)

\frac{3v}{4}=r^{3} (times \frac{3}{4} on both sides)

r=\sqrt[3]{\frac{3v}{4} }

I hope this helps :)
