The circumference of a circle is 138.16 centimeters. What is the area of the circle?
vodomira [7]
Circumference formula tells you C=2 \pi r

<span>C=2 \pi r
</span><span>138.16=2 \pi r
</span>21.99= r
<span>r=21.99cm</span>
The formula to find the area of a circle is A= \pi r^2

<span>A= \pi r^2
</span><span>A= \pi (21.99)^2
</span><span>A= \pi (483.56)
</span>A= 1519cm^2

now take square root on both sides

a

\sqrt{a { }^{2} }  =  \sqrt{725}

a=26.92

Can a positive and negative number be equivalent<br> and plz explain you know it
Sunny_sXe [5.5K]

Answer:

Yes! See explanation below!

Step-by-step explanation:

If a positive and negative number is equivalent, then they are called additive opposites meaning they add up to 0, basically cancelling out.

Ex:

1+-1=0\\1000000+-1000000=0\\\frac{1234}{1234}+-\frac{1234}{1234}=0
