A semi circular window has a diameter of 1.4 meters. What is the total length of the frame required for this window?
Show answer & explanation
Correct answer: B
Explanation
Radius = 1.4/2 = 0.7 meters
Total length of the frame = Circumference of the semicircle + Diameter
= πr + 2r
= 22/7 × 0.7 + 1.4
= 2.2 + 1.4
= 3.6 meters
