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)
b...............................................................................
Answer:
b. Is because -3 because the the negative gets turned into a positive.
5. They are almost the same because subtraction change the negative to a positive and the -5+2 is the aftermath of what happend.
6. Its because the subtract a negative it cancels out and makes the number a positive.
Answer:
Option A
Step-by-step explanation:
V1 = (1/3) π r² h
V2 = (1/3) π ( r/2 )² (2h)
V2 = (1/6) π r² h
V2 = (1/2) V1______Option A
