a)
d/2 = r
10/2 = r
5cm = r
V= (π . r . r).hr
V= 3.14 . 5 . 5 = 78.5cm²
V= 7.85cm² . 20cm= 157cm³
V= 7.85cm² . 20cm= 157cm³
b)
d/2= r
1/2= r
0.5m= r
V= (π . r . r).h
V= 3.14 X 0.5 X 0.5 = 0.785cm²
V= 0.785cm² . 1 = 0.785cm³
V= 0.785cm² . 1 = 0.785cm³
c)
d/2= r
18/2= r
9cm= r
V= (π . r . r).h
V= 3.14 . 9 . 9= 254.34cm²
V= 254.34cm² X 7.5cm= 1907.55cm³
First Container
d/2= r
20/2= r
10cm= r
V= (π . r . r).h
V= 3.14 . 10 .10= 314cm²
V= 314cm² X 40cm= 12560cm³
Second Container
d/2= r
30/2= r
15cm= r
V= (π . r . r).h
V= 3.14 X 15 X 15= 706.5cm²
V= 706.5cm² X 20cm= 14130cm³
V= 706.5cm² X 20cm= 14130cm³
Great job, Jieram! You did an excellent on explaining everything! Next time add a simple sentence for any word problem.
ReplyDeleteGood job Jieram. Whenever you solve a word problem, you should have a simple sentence just like Duyen said.
ReplyDeleteGreat Job Jieram. Your post was great because you showed the work you did for the questions. Next time it would be better if you followed the formulas for some problems and add a video and a link.
