Illustrate a scene with a full, cylindrical water tank outdoors during the daytime. The tank is metallic and 70cm in diameter, filled to the brim with clear, reflective water. Beneath it, one can see a small, steady stream of water leaking, forming a puddle on the ground. There's a floating marker inside the tank showing the water level drop by 20cm. The sky above is bright, underscoring the passing of time, with visible shift from morning to slightly past noon sun.

A cylindrical water tank is 70cm in diameter to begin with it is full of water a leak starts in the bottom so that it looses 10 litres every 1 hour how long will it take for the water level to fall by 20cm.

a 1-cm thick layer of water has a volume of π*35^2 cm^3 = 3.848 L

So, you want to know how long it takes to drain 20cm = 76.97L

76.97L ÷ 10L/hr ≈ 7.7 hr

So, this is it.

We are asked to determine how long it'd take for 20cm of water to be displaced.

We have r=35cm.
If we take a height of 1 cm, the volume of that would be
3.14 x 35^2 x 1 = 3,846.5cm^3.
3,846.5cm^3 = 3.85L (2 d.p)

For height of 20cm, the volume would be
3.14 x 35^2 x 20 = 76,930cm^3
76,930cm^3 = 76.93L

so, 10L lost in 1 hr, 76.93L will be lost in
76.93/10 = 7.693hrs.

Pls explain better 😕🙁

Please who understands this???

I didn't see the workings

Last explanation very explanatory.

Kudos

Thanks for the explanation. it really helps a lot

Explain better

EXPLAIN BETTER

Working is not too explanative

thanks for the update

Please use 22/7 as pie,thanks

am not understanding

Thanks

Nothing

thank you but what does the caret mean

In mathematics, the caret symbol (^) is often used to denote exponentiation. For example, 2^3 means 2 raised to the power of 3, which is equal to 2 x 2 x 2 = 8.

3.14 x 35^2 x 1 means what

In the expression 3.14 x 35^2 x 1, the caret symbol (^) represents exponentiation. It means that the number 35 is raised to the power of 2. So, 35^2 means 35 raised to the power of 2, which is equal to 35 x 35 = 1225. Therefore, 3.14 x 35^2 x 1 means 3.14 multiplied by 1225 and then multiplied by 1.
