a regular pentagon has an apothem of 7.43 cm. Find the length of a side of the pentagon and the length of the radius of the circ
Neko [114]
You have to figure it out.  First, the sum of the angles in a polygon = n-2(180) where n is the number of sides.  For a pentagon, this is 5-2(180)=540.  then divide by 5 for each of 5 large angles in the pentagon, and then divide by 2 for the angle formed by the radius in the right angle.  This is 540/5=108 divided by 2 = 54 degrees in the right angle.  Now that you know the angle , then use trig to solve the problem...

A checkers board is eight squares long and eight squares wide. The area of each square is 14 cm². Estimate the perimeter of the
Tamiku [17]

Answer:

Perimeter of the board is 119.7 cm.

Step-by-step explanation:

We are given that,

Area of each square = 14 cm²

i.e. Side^2=14

i.e. Side= \sqrt{14}

i.e Side = 3.74 cm

So, we get the side of each square is 3.74 cm.

Since, Perimeter of a square = 4a

→ Perimeter of each square = 4\times 3.74

→ Perimeter of each square = 14.96 cm

<em>Since, there are 8×8= 64 squares on the board.</em>

Thus, the perimeter of the board = 8 × Perimeter of each square.

i.e. Perimeter of the board = 8 × 14.96

i.e. Perimeter of the board = 119.68 cm

Hence, the perimeter of the board rounded to the tenths is 119.7 cm.
