Answer:

See below

Step-by-step explanation:

a = 15 sqrt 2 sin 45

= 15 sqrt 2 * sqrt( 2 ) /2 = 15 * 2 /2 = 15

sin 60 = a/c

sqrt(3)/2 = 15/c

c = 15 / ( sqrt(3)/2) = 30 / sqrt 3 = 30 sqrt 3 /3 = 10 sqrt 3

<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,

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

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

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

$V=972\pi$
