Work out the area of a semi circle with a radius of 3cm<br> give your answer in terms of pi
Ivenika [448]
<h3>The area of semicircle is 4.5 \pi\ cm^2</h3>

<em><u>Solution:</u></em>

Given that,

We have to find the area of a semi circle with a radius of 3 cm

<em><u>The area of semicircle is given as:</u></em>

Area\ of\ semicircle = \frac{ \pi r^2}{2}

Where, r is the radius

From given,

r = 3 cm

<em><u>Substituting the values we get,</u></em>

Area\ of\ semicircle = \frac{ \pi \times 3^2}{2}\\\\Area\ of\ semicircle = \frac{ \pi \times 9}{2}\\\\Area\ of\ semicircle = 4.5 \pi

Thus the area of semicircle is 4.5 \pi\ cm^2
