Question

Find the area of figure using 3.14 for pi. round your answer to nearest tenth if necessary.

Answer 1

Given a figure to find the area of the figure.

The given figure is the combination of two triangles and a semi-circle.

Here the radius and the base of the triangle is 10 yd and the height of the triangle is 21 yd. So, the area of the figure is;

`\begin{gathered} A=2*(1)/(2)*\text{base}*\text{height}+(\pi r^2)/(2) \\ =10*21+(3.14*10^2)/(2) \\ =210+(314)/(2) \\ =210+157 \\ =367 \end{gathered}`

Thus, the area of the figure is 367 yd^2.
