You will use this formula $\Large V = \frac{1}{3}\pi*r^2*h$ where r = radius h = height pi is approximately 3.14

3. anonymous

oh um

4. anonymous

still confused

5. jim_thompson5910

do you see how r = 5 and h = 11 ?

6. anonymous

ya

7. jdoe0001

so plug them in the formula

8. anonymous

so 5 times 5 ti,es 11?

9. jim_thompson5910

Yes correct $\Large V = \frac{1}{3}\pi*r^2*h$ $\Large V = \frac{1}{3}\pi*5^2*11$ $\Large V = \frac{1}{3}\pi*25*11$ Do you see how to finish up?

10. anonymous

no sorry i dont

11. jim_thompson5910

25 times 11 = 275 then you multiply 275 by 1/3 to get ???

12. anonymous

something with the fraction right?

13. anonymous

ummm 91.6

14. jim_thompson5910

now multiply that with the value of pi, which is approx 3.14

15. jim_thompson5910

16. anonymous

ya

17. jim_thompson5910

turns out that $\Large 91.\bar{6} = 91 \frac{2}{3}$

18. anonymous

ohh

19. jim_thompson5910

so $\Large V = \frac{1}{3}\pi*25*11$ $\Large V = 91.\bar{6}\pi$ $\Large V = 91 \frac{2}{3}\pi$

20. jim_thompson5910

Another way to get 91 & 2/3 is to do 275/3 = 91 remainder 2 The 91 is the quotient The remainder of 2 forms the numerator over 3

oh okay thank you!!!
