A(n,s)=(ns^2)/(4tan(180/n)), n=number of sides, s=side length
A(8,4.6)=(8*4.6^2)/(4tan22.5)
A(8,4.6)=42.32/tan22.5 m (exact)
A(8, 4.6)≈102.17 m^2 (to nearest hundredth of a square meter)
Answer:
180
Step-by-step explanation:
A=1/2*b*h
A= 1/2*8*25
180
Answer:
Perform Multiplication
9+−6−6
Simplify
‐3
Step-by-step explanation:
First multiply -3 by -3 which equals 9. Then multiply 2 by -3 which equals -6. then put it together to get 9+-6-6. Finally do 9+-6=3-6=-3.
