<u>QUESTION 1</u>

The volume of a cone is given by;

V=\frac{\pi r^2h}{3}


From the given information,

r=12,h=6


V=\frac{12^2\times 6}{3}\pi


V=\frac{144 \times 6}{3}\pi


V=288\pi


<u>QUESTION 2</u>


The volume of a sphere is given by

V=\frac{4\pi r^3}{3}


From the given information.\

r=\frac{Diameter}{2}= \frac{12}{2}=6



Therefore the volume of the sphere is


V=\frac{4\times6^3}{3} \pi


V=\frac{4\times216}{3} \pi


V=288\pi



<u>QUESTION 3</u>


The volume of a sphere is given by

V=\frac{4\pi r^3}{3}


From the given information.\

r=9



Therefore the volume of the sphere is


V=\frac{4\times 9^3}{3} \pi


V=\frac{4\times 729}{3} \pi


V=972\pi


<u>QUESTION 4</u>

The volume of a cylinder is given by


V=\pi r^2 h


From the given information,

r=\frac{Diameter}{2}= \frac{12}{2}=6


and

h=27


Therefore volume of the cylinder


V=6^2 \times 27 \pi


V=36 \times 27 \pi


V=972\pi


<u>QUESTION 5</u>


The volume of a cylinder is given by


V=\pi r^2 h


From the given information,

r=\frac{Diameter}{2}= \frac{8}{2}=4


and

h=18


Therefore volume of the cylinder


V=4^2 \times 18 \pi


V=16 \times 18 \pi


V=288\pi






<u>QUESTION 6</u>


The volume of a cone is given by;

V=\frac{\pi r^2h}{3}


From the given information,

r=\frac{18}{2}=9,h=36


V=\frac{9^2\times 36}{3}\pi


V=\frac{81 \times 36}{3}\pi


V=972\pi

Answer:

5 {x}^{2}  + 3 {x}^{2}  + 6x = 3x - 6x + 9x \\ 8 {x}^{2}  + 6x =  - 3x + 9x \\ 8 {x}^{2}  + 6x = 6x \\ 8 {x}^{2}  = 6x - 6x \\ 8 {x}^{2}  = 0 \\ x = 0 \\ thank \: you

 3oz - 2.5oz = 0.5oz
 Answer:
 
b. no, hildy did not get a reasonable amount of liquid because she only needed 0.5 oz (3 - 2.5 = 0.5).
