What effect does doubling the radius of a cone's base have on the cone's volume?

1 answer:

8 0

Volume of the cone:
V = 1/3 r² π h
If we double the radius:
V 1 = 1/3 ( 2 r )² π h = 4 · 1/3 r² π h
V 1 = 4 V
Answer: the volume becomes 4 times larger.

1)

neverminding how many grams or liters...or whatever unit for now
we know one bag of grass covered 1/6 of the lawn, "a whole" or 1, is 6/6
if 1 bag covers 1/6, to cover 6/6 is just 1/6 +1/6 +1/6 +1/6 +1/6 +1/6 , or 6 bags

2)

one can was enough for 1/4 of the sprayer, a full sprayer is 1 whole or 4/4, so 1/4 + 1/4 + 1/4 + 1/4 or 4 cans

3)

one potato gives enough for 1/3 for a lighbulb, again, 1 whole is 3/3, so 1/3 +1/3 +1/3 , so 3 potatoes

Look at the graphs and their equations below. Then fill in the information about the leading coefficients A overline B Cand D

Tresset [83]

Explanation

,the leading term is the term containing the highest power of x. The coefficient of the leading term is called the leading coefficient.

$\begin{gathered} ax^2+bx+c=0 \\ a\text{ is the leading coefficient} \end{gathered}$

Step 1

an easy way to tell whether the graph of a quadratic function opens upward or downward: if the leading coefficient is greater than zero, the parabola opens upward, and if the leading coefficient is less than zero, the parabola opens downward.

therefore

$\begin{gathered} graph\text{ A}\Rightarrow open\text{ downward}\Rightarrow negative \\ graphB\operatorname{\Rightarrow}open\text{upwards}\operatorname{\Rightarrow}pos\imaginaryI t\imaginaryI ve \\ graphC\operatorname{\Rightarrow}\text{ open upwards}\Rightarrow positive \\ graphD\operatorname{\Rightarrow}open\text{downward}\operatorname{\Rightarrow}negat\imaginaryI ve \end{gathered}$

Step 2

b)the leading coefficient "a" indicates how "fat" or how "skinny" the parabola will be.

for

$\begin{gathered} \lvert{leading\text{ coefficent}}\rvert>1,\text{ the parabola will be ''skinny''} \\ \lvert{\text{leadin coefficien}}\rvert$

hence, more the skinny the graph is, the more closet to zero

therefore,the coefficient closest to 0 is C

Step 3

c)simiary, the graph with the leading coefficient with the grates value will be

graph B

because the coefficient is greater than zero and this graph is the more "fat"

I hope this helps you
