What is the formula of finding area of circle?

anonymous · Answer

idk it doesn't say

nikato · Answer

Ok. But do you know it?

anonymous · Answer

no I don't would you tell me please?

anonymous · Answer

The formula for the area of a circle is A = (3.14)r^2

nikato · Answer

Area=(pi)r^2.  Where r=radius

anonymous · Answer

So since 15 is your radious|dw:1398387116402:dw|

nikato · Answer

Since you know r=15
Just plug it in

A=(15^2)pi

anonymous · Answer

Can you solve form there?

anonymous · Answer

yes thanks everyone you all are the best bye :)

anonymous · Answer

$$A = 706.5 m^{2}$$

anonymous · Answer

@AnyTipzWouldHelp  706.5 is not a choice

nikato · Answer

He multiplied pi which you didn't

It would be whatever 15^2 pi. Is.
He multiplied 3.14 for pi

anonymous · Answer

yes, that is the most common, because pi is an irrational number (goes on forever).
