2) If the circumference of a circle with radius 2.8 cm is 17.6 cm, then the perimeter/
of the semi-circle of the circle is
a) 8.8 cm b) 14.4 cm c) 5.6 cm d) 17.6 cm

​

Answer 1

Answer:

b) 14.4 cm

Step-by-step explanation:

Given,

Radius of circle = 2.8cm

Circumference = 17.6cm

Solution:

perimeter of semi circle = length of diameter + (Circumference/2)

= (2.8 * 2) + (17.6/2)

= 5.6 + 8.8

= 14.4 cm

Therefore, correct option (b)
