Question

Find the perimeter of the semicircular region

22 mm

Answer 1

The permiter is 22mm since its still the same

Explanation:

Answer 2

The Perimeter of the semicircle is 34.54 mm

Using the parameter given ;

• diameter = 22 mm
• Radius = diameter / 2 = 22/2 = 11 mm

Using the formula;

Perimeter of Semicircle = πr

Inputting our values ;

Perimeter = 3.14 × 11 = 34.54 mm

Hence, Perimeter of the Semicircle is 34.54 mm
