Answer:
a: 18pi
b: 3pi
Step-by-step explanation:
part a:
total area = 12^2*pi = 144pi
144pi/8 = 18pi
part b:
total circumference = 12*2*pi = 24pi
24pi/8 = 3pi
The area of each slice from the circel is 18π. The arc length of each side from the circumference of the circle is 3π.
What is the area of a circle?
The area of a circle is an enclosed region within a confined boundary. The area of a circle is measured as the product of π multiplied by the square of a radius.
From the information given:
- The radius of the circle (r) = 12 units
The area of the circle = πr²
The area of the circle = π(12)²
The area of the circle = 144π
However, if the area is divided into 8 congruent(similar and equal) slices, the slice of each area will be:
= 144π/8
= 18π
The circumference of a circle = 2πr
- If the radius = 12
The circumference of a circle = 2π(12)
The circumference of a circle = 24π
The arc length of each side from the circumference of the circle is:
= 24π/8
= 3π
