Use the circle graph to determine how many hours per day Becky spends on each activity.
Oduvanchick [21]
404 error: graph not found

anyway, the graph was not included. since the sleep time was included, I will assume that the circle graph is worth 24 hours

all we need to do is to convert the percentages to fractions and multiply that by 24 to find out how many hours per activity


percent means parts out of 100 so x%=x/100


so we have
School
Eating
Sleep
Homework
Free Time

School=25%
25%=25/100=1/4
1/4 times 24=6
School: 6 hours


Eating=10%
10%=10/100=1/10
1/10 times 24=2.4
Eating: 2.4 hours


Sleep=40%
40%=40/100=4/10=2/5
2/5 times 24=48/5=9.6
Sleep: 9.6 hours


Homework=10%
10%=10/100=1/10
1/10 times 24=2.4
Homework: 2.4 hours


Free Time=15%
15%=15/100=3/30
3/20 times 24=72/20=36/10=3.6
Free Time: 3.6 Hours

School: 6 hours

When looking at the net of a cylinder, what is the relationship between the height of the rectangle and the cylinder?
Nastasia [14]

Volume of a cylinder = πr²h

where,

r is the radius of the cylinder

h is the height of the cylinder

Area of the rectangle = length X breadth

We can consider that a rectangle if rotated will form a cylinder.

In that case, the breath of the rectangle will become the diameter of the cylinder and the length will become the height of the cylinder.
