The diameter of a semicircle is 5.6 m. What is its perimeter (in m, correct to one decimal place)? (Take .)
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 14.4.
Radius of the given semicircle = 5.6/2 = 2.8 m
Circumference of the semicircle = 22/7 × 2.8 + 2 × 2.8 = 14.4 m
Hence, the perimeter of the semicircle = 14.4
