Question 4 options:
Find the perimeter. Use straight pi = 3.14.
Blank Space__________m
This is an illustration of a semi circle labeled with a diameter of eight and two tenth meters.
Type the correct answer.
The perimeter of a semicircle can be found by summing the length of the straight line segment (diameter) and half the circumference of the full circle.
Given a diameter of 8.2 meters, the circumference of the full circle would be π * diameter = 3.14 * 8.2 = 25.708 meters.
Since the semicircle only includes half of the circumference, the perimeter would be given by 8.2 + 0.5 * 25.708 = 21.598 meters.
Therefore, the correct answer is 21.598 m.
