What is the volume of a cone with a radius of 2 and a height of 19?

Remember that the cone volume formula is , with r = radius and h = height. Using our information, we can form our equation as such: (I'll be keeping the answer in pi form.)

Firstly, solve the exponents:

Next, multiply 4 and 19/3 together and your answer should be (rounded to the hundreths): V = 25.33π un^3

step-by-step explanation:

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1
