QUESTION 1

The volume of a cone is given by;

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

From the given information,

$r=12,h=6$

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

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

$V=288\pi$

QUESTION 2

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

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

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

$V=288\pi$

QUESTION 3

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

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

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

$V=972\pi$

QUESTION 4

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

$V=6^2 \times 27 \pi$

$V=36 \times 27 \pi$

$V=972\pi$

QUESTION 5

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

$V=4^2 \times 18 \pi$

$V=16 \times 18 \pi$

$V=288\pi$

QUESTION 6

The volume of a cone is given by;

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

From the given information,

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

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

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

$V=972\pi$

when three different numbers are chosen from the set {-3,-2,-1,4,5) and multiplies the greatest possible product is

larisa86 [58]

1. We cannot pick both of the positive numbers 4 and 5 because the third one would be negative, and the overall product negative.

2. So we pick 5, the largest of (4, 5) and 2 negative numbers

3. Since the multiplication of the 2 negative numbers is positive, we pick the ones with larger absolute value, so -3 and -2

Answer: 5*(-3)*(-2)=5*6=30

Answer:

Hope this helps!!! :)

Step-by-step explanation:

#1: if there is buy 1 get 1 free, then buy 6 get 3 free. so 2.8 times 3 = $8.4

#2: 4 for $3. break it up to 1 for $0.75. now 0.75 times 6 = $4.5

#3: the second one. $4.5 < $8.4

#4: 45 times 12 = $54

Is x ^ 2 + y ^ 2 = 6 a function?

oee [108]

Answer:

not a function

Step-by-step explanation:

for example

In order for an equation to represent a function any single value of x must have at most one corresponding value of y which satisfies the equation.

For x2+y2=9

XXXXif (for example) x=0

XXXXthere are two values for y (namely +3 and −3) which satisfy the equation

and therefore the equation is not a function.
