» Appropriate Question:

Find the perimeter of the adjoining figure which is a semi-circle if it's diameter is 16cm. (Take [tex] π [/tex] = 3.14)

» Solution:

Radius of the given semi-circle

= 8cm

Circumference of given semi-circle

= [tex] (πr + 2r) [/tex]

[tex] = [(3.14×8) + (2×8)] [/tex]

[tex] \red{= 41.12cm} [/tex]

Hence, the circumference is 41.12 cm!!

» Additional Information:

• [tex] \mathtt{Circumference_{(semi-circle)} = (πr + 2r)} [/tex]
• [tex] \mathtt{Circumference_{(circle)} = 2πr} [/tex]
