Answer 1

Question : find the circumference of semi circle of diameter 10 cm


Answer:


Circumference of Semicircle = πD

Circumference of SemiCircle = 22/7×10

Circumference of Semicircle = 31.4 cm²

Answer 2

Answer:

$15\frac{5}{7}$ cm

Step-by-step explanation:

Diameter of the circle is 10cm,

hence the radius(r) is 5cm.

Using the formula of Circumference of a semi-circle,

Circumference= πr

                        = $\frac{22}{7} * 5$

                        = $\frac{110}{7}$

                        = $15\frac{5}{7}$ cm
