Find the perimeter of this semi-circle with diameter, d = 18cm. Give your answer as an expression in terms of pi.
OLga [1]

Answer:

The perimeter of the given semi-circle in terms of \pi is

P=9\pi cm

Step-by-step explanation:

Given that the diameter of the semi-circle is 18cm

That is d=18cm

Therefore radius r=\frac{d}{2}

r=\frac{18}{2}

Therefore radius r=9cm

To find the perimeter of the semi-circle :

perimeter of the semi-circleP=\pi r

P=\pi\times 9 cm (where r=9 cm )

P=9\pi cm

The perimeter of the given semi-circle in terms of \pi is

P=9\pi cm
