Question

Find the area of the SIM circle round the to the nearest 10th used 3.144 pi do not include units with your answer 12 in

Answer 1

`\text{area of semi circle }=(1)/(2)\pi r^2`

r = 12 units

`\begin{gathered} \text{area}=(1)/(2)*3.14*12^2 \\ \text{area}=(1)/(2)*3.14*144 \\ \text{area}=(452.16)/(2)=226.08 \\ \text{area}=226.1 \end{gathered}`
