A circular pizza of radius 8 is cut into 8 equal slices. What is the perimeter of one slice?
Is it 16 + 2(pi)
yes
If each side of a square is increased by 50% the area of the square is increased by ____% ?
To find the perimeter of one slice of the circular pizza, we need to determine the length of the curved edge of a slice.
First, we calculate the circumference of the entire pizza using the formula for the circumference of a circle, which is given by:
Circumference of a circle = 2 * π * r
Where:
- π (Pi) is a mathematical constant approximately equal to 3.14159
- r is the radius of the circle
Given that the radius of the circular pizza is 8:
Circumference of the pizza = 2 * π * 8
Let's calculate the value of the circumference of the pizza:
Circumference of the pizza = 2 * 3.14159 * 8
Using a calculator, we get:
Circumference of the pizza ≈ 50.2655
Since the pizza is divided equally into 8 slices, each slice will cover 1/8th of the circumference of the pizza.
Perimeter of one slice = Circumference of the pizza / Number of slices
Perimeter of one slice = 50.2655 / 8
Calculating this:
Perimeter of one slice ≈ 6.28319
Therefore, the perimeter of one slice of the circular pizza is approximately 6.28 units (rounded to two decimal places).
