A regular heptagon has a radius of approximately 27.87 cm and the length of each side is 24.18 cm. What is the approximate area
of the heptagon rounded to the nearest whole number? Recall that a heptagon is a polygon with 7 sides.
2 answers:
If you know the side length, you don't need the radius to calculate the area. The area for any regular polygon is:
A(n,s)=(ns^2)/(4tan(180/n)), where n=number of sides and s=length of sides.
The above is derived by dividing the polygon into n triangles...anyway, in this case:
A=(7*<span>24.18^2)/(4tan(180/7)
A=</span>1023.1767/tan(180/7)
A=2124.65 cm^2 (to nearest one-hundredth)
Answer:
.
Step-by-step explanation:
We have been given that a regular heptagon has a radius of approximately 27.87 cm and the length of each side is 24.18 cm.
We will use area of a heptagon formula to find the area of our given heptagon.
, where, a represents each side of heptagon.
Upon substituting a=24.18 cm we will get,




Therefore, area of our given heptagon will be approximately

Answer
product is rational
cause
4.5 (5repeat) = 41/9
so
41/9 x 456/100 = rational
90/12 = 7.5

5x-3x=-6
2x=-6
x=-3
x equals -3 is the answer.
The first blank is "division" and the second blank is "multiplying"
12 / (3) = 4
5 x 3 = 15
15 + 4 = 19
