## anonymous 5 years ago A right circular cylinder with the height of T. The radius of the base is the square root of Q?

1. anonymous

Sounds good. I'll take it!

2. anonymous

can u show me the equation

3. anonymous

The equation for what?

4. anonymous

of the question(up there)

5. myininaya

do you want volume of the cylinder?

6. anonymous

You've just described a cylinder. What do you want to know about it?

7. myininaya

surface area?

8. anonymous

umm either one of them

9. myininaya

Volume=pi*r^2*h=pi*(sqrt(x))^2(T)=pi*x*T

10. anonymous

11. myininaya

x=Q sorry

12. anonymous

Volume of a cylinder $$= Area_{base} * Height$$ Area of a circle $$=\pi r^2$$

13. anonymous

So if Height = T and r = Q. What is the Volume of your cylinder?

14. anonymous

I don't how to do this can u show the step so I can know what the volume of this

15. anonymous

The volume of a cylinder is the (Area of the base) times (the height). The base is a circle. The area of a circle = $$\pi * (radius^2)$$. $$\pi \approx 3.14159$$ The radius of the base of your cylinder = $$\sqrt{Q}$$. The height of your cylinder = T. Using the statements above you can easily compute the volume of your cylinder. Please study what I've said carefully and see if you can figure out how to do this.

so i use $\pi \times \sqrt{Q}$^2 then what next

17. anonymous

Simplify that.

18. anonymous

$$\pi * \sqrt{Q}^2 = \pi * Q$$

19. anonymous

What is that value in relation to your cylinder?

20. anonymous

what that mean

21. anonymous

You use $$\pi * Q$$ for what?

22. anonymous

Qpi
