Answer: The lenght of the missing side is 4 cm
Step-by-step explanation:
The correct question is:
<em>The perimeter of the rectangle is 20cm . One side is 6cm. What is the length of the missing side?</em>
So, to answer it we have to apply the next formula:
Perimeter of a rectangle = 2 width + 2 length
Replacing with the values given: (assuming that the side given is the length of the rectangle)
20 = 2(6) + 2x
Solving for x:
20 =12 +2x
20-12 =2x
8 =2x
8/2 =x
4=x
The length of the missing side is 4 cm

Step-by-step explanation:
Given the following data;
Diameter, D = 18 inches
Pie, π = 3.14
To find the circumference of the circle;
Mathematically, the circumference of a circle is given by the formula;
Circumference of circle, C = πD
Where, D is the diameter of a circle.
Substituting into the formula, we have;
C = 3.14 * 18
C = 56.52 inches
