Question

Ques 6. If the perimeter of a semicircle protector is 27cm, find its diameter.
​

Answer 1

Answer:

$d = \frac{189}{11}$

Step-by-step explanation:

perimerter of a semicircle = 27

$\pi \: r = 27$

$\frac{22}{7} \times r = 27$

$r = 27 \times \frac{7}{22}$

$r = \frac{189}{22}$

diameter = 2r

$d = \frac{189}{22} \times 2$

$d = \frac{189}{11}$
