## anonymous 5 years ago i HAVE A PROBLEM AM TRYING TO GET THE CORRECT ANSWER

1. anonymous

S=pie(1.5)$\sqrt{(1.5)^2+(4)^2}$

2. anonymous

5.5

3. anonymous

(1.5+4)^(2/2) 1.5+4

4. anonymous

thats not correct the S= (PIE SIGN) and (1.5) go with the equation

5. anonymous

sara what is the question? write out the whole equation

6. anonymous

s=(3.14)(1.5)$\sqrt{(1.5)^2+(4)^2}$

7. anonymous

the s= part goes with the equation its not ontop like its displaying

8. mattfeury

like this?: $3.14 * 1.5 * \sqrt{(1.5)^2+(4)^2}$

9. anonymous

yes

10. anonymous

which part do you not understand? exponents? square root?

11. anonymous

I got 20.13 but then I di it again and got 20.11 so im confused

12. anonymous

The answer to four decimal places is 20.1313

13. anonymous

ok .. how did you get that so I can do my others correctly?

14. anonymous

3.14 is not the exact value of pi that's probably the cause of your error

15. anonymous

hit the $\pi$ on your calculator instead of typing 3.14

16. anonymous

I cant use a calculator for these so I need to learn how to do them correctly

17. anonymous

well if that's the case i'm sure your 20.11 value is correct enough. I'm sure your teacher doesn't expect you to memorize pi to 20 digits
