## anonymous one year ago Find the area of the circle with the given radius or diameter. Use = 3.14. d = 10 a = ?

1. anonymous

its a trivial question!!!

2. anonymous

What does that mean? Haha. Its multiple choice btw. a. 314 sq. units b. 157 sq. units c. 78.5 sq. units

3. anonymous

area = bi*r^2...so it will be 78.5

4. anonymous

What is bi?

5. anonymous

OMG!!! bi is the ratio between the diameter of any circle and its circumference ....its given in your question = 3.14

6. anonymous

Don't be rude. And what does it stand for? bi isnt just bi.

it's supposed to be "pi" which is the greek letter $$\LARGE \pi$$

8. jim_thompson5910

pi is approximately 3.14
