the total surface area of a solid cylinder is 21cm if the curved surface area of the solid cylinder is two - third of its total

arsen [322]

Answer:

The radius of cylinder is 1.05 cm and

The height of cylinder is 2.11 cm

Step-by-step explanation:

Given as :

The total surface area of cylinder = 21 cm

The curved surface area of cylinder = $\frac{2}{3}$ of the total surface area

I.e The curved surface area of cylinder = $\frac{2}{3}$ × 21 = 14 cm

∵ The total surface area of cylinder = 2 $\pi$ r h + 2 $\pi$ r²

Where r is the radius and h is the height of cylinder

Or, 2 $\pi$ r h + 2 $\pi$ r² = 21 cm

Or, $(2\times \Pi \times r\times h) + (2\times \Pi\times r^{2} )$ = 21 cm ....a

Again ∵ The curved surface area of cylinder = 2 $\pi$ r h

Where r is the radius and h is the height of cylinder

Or, 2 $\pi$ r h = 14 cm . ...b

so . put the value of a into b

I.e 14 cm + $(2\times \Pi\times r^{2} )$ = 21 cm

Or, $(2\times \Pi\times r^{2} )$ = 21 cm - 14 cm

Or, $(2\times \Pi\times r^{2} )$ = 7

so , r² = $\frac{7}{2\pi }$

∴ r² = $\frac{49}{44}$

I.e r = $\sqrt{\frac{49}{44} }$

So, radius = $\frac{7}{\sqrt{44} }$ cm

or, r = 1.05 cm

Put the value of r in eq b

2 $\pi$ r h = 14 cm

Or, 2 $\pi$ × $\frac{7}{\sqrt{44} }$ × h = 14 cm

So, h = $\frac{\sqrt{44} }{\pi }$

Or, h = 2.11 cm

Hence The radius of cylinder is 1.05 cm and The height of cylinder is 2.11 cm Answer

For every 1 litre of water used to make a medicine, 300 ml of sucrose and 750ml of saline solution are used. Express the amount

dexar [7]

Answer:

20ml : 6ml: 15ml

Step-by-step explanation:

1000 milliters is 1 liter, so we would have to convert it to the ml so that it will all be in proportion. To simplify a ratio, divide by a number they can all be divided by. In this case, it was 10 first, so it made it 100: 30: 75. Then, to simplify it more, they can all be divided by 5, which is the lowest it can be since 20: 6: 15 have no numbers in common to be divided by.

Is it a function? Explain

DochEvi [55]

Answer:

Yes.

Step-by-step explanation:

For a graph to be a function, it must have precisely one y-value for every x-value.

In this case, this graph is a function because it meets the requirements of having one y-value for every x-value.
