## UmmmHELP one year ago Find the area. Use π = 3.14

1. UmmmHELP

2. nphuongsun93

area = πr^2 r = d / 2 d = 2.6

3. UmmmHELP

Okay but I dont know how to set up the problem

4. nphuongsun93

you have to find r, the radius, from using the diameter, d. r = d / 2 with d = 2.6 meters

5. UmmmHELP

so its 2.6/2

6. nphuongsun93

then find the area using r, the formula for area is π times r^2

7. UmmmHELP

so then 1.3x2?

8. UmmmHELP

oh does that mean |dw:1360790674220:dw|

9. nphuongsun93

yes $\huge 1.3^2 \pi$

10. UmmmHELP

okay so then its 5.309
