or

96 π

Step-by-step explanation:

on khan acad. if you click on the box, you can click on the pi icon to do it in terms of pi.

I always do in terms, but make sure to learn the other way :)

the formula for cone volume is π r^2  h/3

radius = 6

height = 8

π 6^2  8/3

π 36  8/3

π 36 x 8  /3

π 288 / 3

π 96

Answers:
k = 13The smallest zero or root is x = -10
===============================
Work Shown:
note: you can write "x^2" to mean "x squared"
f(x) = x^2+3x-10
f(x+5) = (x+5)^2+3(x+5)-10 ... replace every x with x+5
f(x+5) = (x^2+10x+25)+3(x+5)-10
f(x+5) = x^2+10x+25+3x+15-10
f(x+5) = x^2+13x+30
Compare this with x^2+kx+30 and we see that k = 13
Factor and solve the equation below
x^2+13x+30 = 0
(x+10)(x+3) = 0
x+10 = 0 or x+3 = 0
x = -10 or x = -3
The smallest zero is x = -10 as its the left-most value on a number line.
