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.

In the xy coordinate plane, the slope of a line is 4 and it passes through the point (1, 3). Find the equation of a line that is
igor_vitrenko [27]

Answer: Y=-1 or Y=-1+4

Step-by-step explanation:

<h3>Use the formula y2- y1 over x2-x1 so it should look like this 1-3 over 3-1 which is -2 over 2 then you divide that which is -1 and if you have to find one all you have to do is use one point label which is x and y so I pick (1,3) so you put 3=-1(1) once you have that you multipy so -1 times 1 is -1 so your gonna add 1 to the -1 and the three the -1 cancel out because it is a zero pair 3+1 is 4 so B=4 </h3>
