You don't need the apothem if the side length is known, the area can be expressed as:
A(n,s)=ns^2/(4tan(180/n)), n=number of sides and s=side length so
A(7,28)=(7*28^2)/(4tan(180/7))
A≈2848.987 ft^2
A≈2849 ft^2 (to the nearest tenth of a square foot)
Answer:
c = 7
Step-by-step explanation:
6c = 7c - 7
Subtract 6c to both sides
0 = c - 7
Add 7 to both sides
c = 7
Answer:
1. 102 ft^2 2. 33 ft^2 3. 112 ft ^2
Step-by-step explanation:
you have to find the area of each section of each shape, then add
The correct answer is maybe 3
From cm to km you divide the number by 100000
So 35,000/100000 = 0.35km
