Find the area of this regular polygon round to nearest tenth

Mathematics
1 answer:
Bezzdna [24]3 years ago
4 0

Answer:

A=163.9in^2

Step-by-step explanation:

Let's use the regular polygon area formula when given the radius.

A=\frac{(r^{2})(n)sin(\frac{360}{n})}{2}

r is radius

n is the number of sides

Let's plug in the proper values into this equation and simplify:

A=\frac{(7.74^{2})(7)sin(\frac{360}{7})}{2}

A=\frac{(59.9076)(7)(0.78183148)}{2}

A=\frac{327.86353299}{2}

A=163.93176649

SpyIntel [72]

Answer:

= 1700 :)

Step-by-step explanation:

-multiply all the sides,

-add them,

- then double the answer (or times it  by 2):

1) 30 times 20 = 600

30 times 5= 150

20 times 5 =100

2) Add them:

600+150+100 = 850

then times 850 by 2

850 times 2 = 1700
