A quadrant has a radius of 33 m. Find the perimeter of the quadrant. Take π as 3.14.
Question
A quadrant has a radius of 33 m. Find the perimeter of the quadrant. Take as 3.14.
Solution
To find the perimeter of a quadrant, we need to add the length of the arc (which is a quarter of the circumference of the full circle) and twice the radius (which represents the two straight sides of the quadrant).
Step 1: Find the circumference of the full circle. The formula for the circumference of a circle is 2πr. Here, r is the radius, which is given as 33 m. So, the circumference is 2 * 3.14 * 33 = 207.24 m.
Step 2: Since a quadrant is a quarter of a circle, the length of the arc of the quadrant is a quarter of the full circumference. So, the length of the arc is 207.24/4 = 51.81 m.
Step 3: The perimeter of the quadrant is the sum of the length of the arc and twice the radius. So, the perimeter is 51.81 + 2*33 = 117.81 m.
So, the perimeter of the quadrant is 117.81 m.
