The answer is 8
To work out you do :
6+12+7+5+11+6+9 which equals 56
Then you count how many numbers there are so that’s 7 and then you do 56 divided by 7(so the total of the numbers added and the amount of numbers there are) and then you get your answer :)

Sandra has a cylindrical mold for making candles with a radius of 3.4 cm and a height of 6 cm. If Sandra uses a rectangular bloc

Wittaler [7]

Answer:

$14\ candles$

Step-by-step explanation:

step 1

Find the volume of the cylindrical mold

The volume is equal to

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

we have

$r=3.4\ cm$

$h=6\ cm$

assume

$\pi=3.14$

substitute

$V=(3.14)(3.4)^{2}(6)$

$V=217.79\ cm^{3}$

step 2

Find the volume of the wax

The volume is equal to

$V=(15)(12)(18)$

$V=3,240\ cm^{3}$

step 3

Divide the volume of the wax by the volume of the cylindrical mold, to calculate the number of candles

$3,240/217.79=14.9\ candles$

Round down

$14\ candles$
