Lila do you know the formula to solve for the area of a circle?

eyust707 · Answer

Use the same formula I taught you
$$Area = \pi * r * r$$

mrnood · Answer

I guess you have in oyur study a formula for th earea of a circle

It has only pi and r in the formula.

Using r = 14 and pi = 3.14 and a calculator and the formula - you can work it out....

eyust707 · Answer

You got the last one I have a feeling you can get this on too!

shadowlegendx · Answer

$$π\times 14^{2}$$

shadowlegendx · Answer

$$3.14 \times 14^{2}$$

mrnood · Answer

@ShadowLegendX  Maybe the rest should be done by lila????

shadowlegendx · Answer

Follow orders of operations (PEMDAS) and solve for $$14^{2}$$ first

shadowlegendx · Answer

A person can not do a problem that they have never seen done before

mrnood · Answer

given ALL the information above they should make an effort

shadowlegendx · Answer

They atleast need assistance with the first couple steps

Thanks @ShadowLegendX 
@eyust707 I remember the formula. So I do the same with this one?

anonymous · Answer

@MrNood Sorry my internet was acting up, that's why I wasn't making an "effort"

mrnood · Answer

np - but you have all you need now to calculate this

shadowlegendx · Answer

Lila what did you get?

anonymous · Answer

Okay what if i was still confused and couldn't solve it

anonymous · Answer

Still calculating TI-32 is acting up now

mrnood · Answer

@ShadowLegendX The real world is FULL of problems that we've never seen before. The purpose of study is to learn how to extrapolate what we DO know to interpret that which we don't know

shadowlegendx · Answer

Lila you just need to solve for $$3.14 \times 14^{2}$$

shadowlegendx · Answer

3.14 is Pi(π)

$$14^{2}$$ is the radius

mrnood · Answer

I suggest you do it in your head - it says ESTIMATE

You can do 14 x 14 in your head - then multiply by 3 - see which answer is closest.
