Answer:
452.2 cm
Step-by-step explanation:
A = 4πr²
A = 4 (3.14) (6)²
A = 4 (3.14) (36)
A = 452.16
A = 452.2 cm (nearest tenth)
Answer:
-8.0625
Step-by-step explanation:
D. 80
If you expand the entirety of the polynomial, you get the following:
32x^5+80x^4y+80x^3y^2+40x^2y^3+10xy^4+y^5
L=w+2 and 2w+2l=40
Substitute length for w+2 in perimeter formula.
2w+2(w+2)=40
2w+2w+4=40
4w+4=40
4w=36
w=9
l=w+2
l=9+2
l=11
a=lw=11*9=99 meters
