Answer: circumference of the circle is 11.31 meters

C=\pi d\\C=\pi (2r)\\C=2\pi r

Where radius (r) is half of diameter (d)

Since radius of the circle shown in 1.8m, we plug it in the formula and get:

C=2\pi r\\C=2\pi (1.8)\\C=11.31

So C = 11.31 meters

In a certain hexagon, the two shortest sides have the same length. The length of each remaining side is 2 inches more than the l
Nonamiya [84]

Answer:

length of the shortest side = 5 inches

length of the longest side is 7 inches

Step-by-step explanation:

Hexagon has 6 sides

Let x be the shortest side

length of the longest side is x+2

there are 2 shortest sides and 4 longest sides

To find perimeter we add all the sides

Perimeter = 2(x) + 4(x+2)

38= 2(x) + 4x+8

38=6x+8

Subtract 8 from both sides

30=6x

divide both sides by 6

x=5

length of the shortest side = 5 inches

length of the longest side is 7 inches
