The perimeter of each region is 12 + 1.5π if a circle with an area of 36π is divided into 8 congruent regions
What is an equation?
An equation is an expression that shows the relationship between two or more numbers and variables.
Let r represent the area of the circle, hence:
Area = πr²
36π = πr²
r = 6 units
Perimeter = 2πr = 2π(6) = 12π
The circle has 8 congruent regions, hence:
Perimeter of each region = 6 + 6 + 12π/8 = 12 + 1.5π
The perimeter of each region is 12 + 1.5π if a circle with an area of 36π is divided into 8 congruent regions
