Question

1. If a cylindrical water tank has the dimensions shown in the figure, calculate the amount of sheet metal needed to create this tank. (Hint: Calculate the surface area of the cylinder.) 2.Calculate the volume of water that this cylindrical tank will hold.

Answer 1

SA=circumference x ht + 2 x base area

Answer 2

Vol=pi x r^2 xht

Answer 3

Sheet of metal needed to make this tank
1. 94.5 π m²
Calculate the volume of water this cylinder tank will hold
2. 122.5 π m³

Answer 4

Both of those are not options.

Answer 5

Anyone get it?

Answer 6

SA=140pi or approx. 440

Answer 7

The options for question one are:
1.59.5pi
2.168pi
3.82.25
4.115.5pi
For number 2:
1.490pi
2.182pi
3.91pi
4:159.25

Answer 8

Sorry. I miscalculated.

SA=115.5 pi

Answer 9

Are you sure?

Answer 10

Yes.

Answer 11

Yeah I got that one now

Answer 12

K for volume what did you get?

Answer 13

Question: Is your 4th choice for number 2 supposed to be 159.25 "pi" ?

Answer 14

Alright that checks through with everything I did thanks!

Answer 15

Nice!
