A cone has volume of 12\pi cubic inches. Its height is 4 inches. What is its radius?

asambeis [7]

The radius of cone is 3 inches.

Step-by-step explanation:

Given,

Volume of cone = 12π cubic inches

Height of cone = 4 inches

Let,

r be the radius of cone.

Volume of cone = $\pi r^2\frac{h}{3}$

$\pi r^2\frac{4}{3}=12\pi$

Multiplying both sides by 3

$3*\pi r^2\frac{4}{3}=12\pi * 3\\4\pi r^2 =36\pi$

Dividing both sides by 4π

$\frac{4\pi r^2}{4\ pi}=\frac{36\pi }{4\pi }\\\\r^2=9$

Taking square root on both sides

$\sqrt{r^2}=\sqrt{9}\\r=3$

The radius of cone is 3 inches.

What is 965,000,000,000,000 in scientific notation

Genrish500 [490]

Scientific notation is the way that scientists easily handle very large numbers or very small numbers. For example, instead of writing 0.0000000056, we write 5.6 x 10-9.

So, if we are dealing with 965000000000000, then the answer would be:

9.65 x 10^14
