A= anl, where
A = area
a = apothem
n = number of sides
1 = length of sides
If a regular polygon has an area of 180 cm2, an apothem of 6 cm and sides 12 cm in
length, how many sides does it have?

5 sides

Step-by-step explanation:

Area=1/2aP

180=1/2(6)(12x)

3(12x)=180

36x=180

x=5

4 flowers

Step-by-step explanation:

-Circumference of a circle formula: dπ (diameter times pi)

-So plug 3.14 for π and 20 for the diameter to solve it:

20(3.14)  which equals 62.8

-Do 62.8 divided by 15.7 to find how many flowers are around the edge (circumference):

62.8 ÷ 15.7, which equals 4

4 flowers
