Answer:
Peter should join <u>Lab thinkers</u> to receive a better deal.
Science buddies costs <u>190$</u> for six months.
Lab thinkers costs <u>170$</u> for six months.
Step-by-step explanation:
The equations are...
Science buddies: 10+30x -> 10+30(6)=190
Lab thinkers: 45+25x -> 45+25(6)=170
Peter saves 20$ if he chooses lab thinkers.
Sorry for my mistake, this is my new edit.
Answer:
V = Π (4)2*12
V = 603.19 cm3
Step-by-step explanation:
A soup can is a cylinder.
The formula for volume of a cylinder is the following: V= Πr2h.
We are given the height which is 12 (h=12) and the diameter which is 8 (d=8).
The formula asks for radius so we divide the diameter by 2.
r =8/2 = 4.
Now we can just plug the numbers into the formula
V = Π (4)2*12
V = 603.19 cm3
Since the units of measure are in centimeters, the volume will be measured in cubic centimeters.
