Answer:
Step-by-step explanation:
12² + 4x = 0
144 + 4x = 0
subtract 144 from both sides
144 + 4x - 144 = 0 - 144
4x = -144
divide both sides by 4
![\frac{4x}{4}=\frac{-144}{4}\\\\x=-36](https://tex.z-dn.net/?f=%5Cfrac%7B4x%7D%7B4%7D%3D%5Cfrac%7B-144%7D%7B4%7D%5C%5C%5C%5Cx%3D-36)
Volume of the cone = 1/3 pi * 3^2 * 4 = 12pi
Volume of the hemisphere = 4/3 pi 3^3 * 1/2 = 18pi
So the volume of the toy = 12pi + 18pi = 30pi = 94.25 cm^3 to nearest hundredth Answer
Surface area of hemisphere = 1/2 * 4 pi 3^2 = 18pi
Lateral Surface area of the cone = pi r l where l = slant height of the cone
Now l= sqrt ( 4^2 + 3^2) = sqrt25 = 5
So lateral S A = 3 * 5 * pi = 15pi
Surface area of the toy = 18pi + 15pi = 33pi = 103.67 cm^2 ( nearest hundredth) Answer
Wouldn’t it be 6,054 it so easy
%change=100(572-650)/650= -12%
The sales decreased by 12%
