The figure is made up of a cone and hemisphere. To the nearest whole number, what is the volume of this figure? Use 3.14 to approximate pi. Round only your final answer to the nearest whole number.

Volume=469cm³

Step-by-step explanation:

[tex]

Volume,V=Volume Cone + Volume\ of Hemisphere\\\\

Volume Cone,V1=\pi*r^2*\frac{h}{3}=\pi*4^2*\frac{12}{3}\\    \\

                     =201.06cm^3\\

Volume of Hemisphere,V2=2*\pi*\frac{r^3}{3}\\

                                            =2*\pi*\frac{4^3}{3}=268.083cm^3\\

Volume=V1+V2=201.06+268.08\\

            =469cm^3

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
