Problem
016.2 Arc Length and Radian Measure - REVISION Question The dilagram shows the plan for putting a decorative trim around a corner desk. The trim will be 4inch high around the perimeter of the desk. The curve is one quarter of the circem high around the perimeter of the desk. The curve is one quarter of the circumference of a circle. Find the length of trim needed to the nearest half foot. The length of trim needed is feet. Question 19 of 21
Solution
Step 1 ：Find the circumference of the circle using the formula C = 2 * pi * r, where r is the radius (4 inches): C = 2 * \(\pi\) * 4
Step 2 ：Divide the circumference by 4 to get the length of the curve: \(\frac{C}{4}\)
Step 3 ：Convert the curve length from inches to feet: \(\frac{curve\_length}{12}\)
Step 4 ：Round the curve length in feet to the nearest half foot: \(\boxed{0.5}\)
