In this discussion, you have the opportunity to have some hands-on fun. With a
tape measure determine the diameter and circumference of at least three circular
objects. Calculate the ratio of the circumference to the diameter.
Take a look at Khianna's post:
I used a tape measure to determine the diameter and circumference of an orange
juice can, a trash can, and a lamp shade. Here is what I found:
Circumference
4.65 in
Ratio
3.1
OJ Can
Diameter
1.5 in
8 in
6 in
Trash Can
3.12
24.96 in
18.8 in
Lamp Shade
3.13
The ratio was close to Pi, but never actually equaled 3.14, maybe because of an
error when I measured the objects.
After you complete your measurements, use the diameter to calculate the exact
circumference of each object as shown on the next page.
Use the diameter to calculate the exact.value of the circumference of each object.
Look how Khianna added to her post:
If I used the diameter I measured, the exact value for each object's circumference would be: diameter or circumference OJ can 1.5 in 1.5 pi and 4.71 in trashcan eight in a pie in 25.12 in lampshade six and six pie and 18.84 in
Use a measuring tape to determine the diameter and approximate for conference of three household items
Find the ratio of the circumference to the diameter for each circle identify what the value of this ratio should be
Use pi and the diameter to calculate the exact value of the circumference
Use the approximation pi equals 3.14 to find the approximate circumference

Drug Name Half-life
-----------------------------------
Acetaminophen 1-4 hours
Ibuprofen 1.8-2 hours
Loratadine 8.4 hours
Lithium 8 hours
Diphenhydramine 5.3-11.7 hours

The table above displays the half-lives of 5 common house hold drugs. The half-life (h) is the time is takes for a substance to reduce to half its initial value (A0). Half life can be used to solve for the amount (A) of a substance left after t time by using the following equation:


A=A^0⋅(12)^t/h
