Area=rsquared(pi)
24/2=12(12)=144(pi)
Around 452.16
I hope that is correct.
X^2-8x+16= (x-4)^2 because -4 and -4 add to -8 but multiply to 16. Hope that helped.
Rewrite then factor as a difference of cubes:
1 - 64<em>x</em>³ = 1³ - (4<em>x</em>)³
= (1 - 4<em>x</em>) (1² + 4<em>x</em> + (4<em>x</em>)²)
= (1 - 4<em>x</em>) (1 + 4<em>x</em> + 16<em>x</em>²)
When it’s negative change it to a positive and vice versa. 0 stays 0
1) Take the perimeter and divide it by 4.
2) Take the answer from step 1 and square it (multiply by itself)
