Question

anonymous · Answer

the area formula for a circle is pi * radius ^2

ms-brains · Answer

So C?

anonymous · Answer

yes

dinamix · Answer

10^2*pi = 100pi cuz s= r^2*pi

dinamix · Answer

@Ms-Brains

skullpatrol · Answer

$$\Huge A=\pi r^2$$

skullpatrol · Answer

where r = the radius and A = the area of any circle.

skullpatrol · Answer

$$\Huge r^2 = r•r$$

ms-brains · Answer

The answer is 100 m^2, right? @skullpatrol

anonymous · Answer

this is the formula Area = πr². r = radius btw and  ² = squared

anonymous · Answer

it is the radius x pi to the second power

ms-brains · Answer

So choice C is incorrect?

anonymous · Answer

it is 10π ². Also please forgive me for how long it takes to type these replies since I needed to look up how to type up these symbols.

anonymous · Answer

It is 314.16 meters

ms-brains · Answer

Alright. 314.16 isn't a choice tho..
And it's alright

anonymous · Answer

it is odd though that it is still ² since it shouldn't be if 100 is an answer but I would say just ask your teacher if it was a mistake

ms-brains · Answer

Okay. So You agree that 100 is the answer?

anonymous · Answer

100πm is the answer. Just ask your teacher why it says 100πm²

kayders1997 · Answer

Yes that is the answer @Ms-Brains

ms-brains · Answer

Thank you all!

kayders1997 · Answer

Because it's the area you are squaring the m part twice so you would do 10in)(10in) which is 100in^2

anonymous · Answer

oh yea I forgot that

anonymous · Answer

thx for the reminder
