Question

Find the area of the following figure with the indicated dimensions.use pi.

Answer 1

The answer is "47.5354".

Explanation:

In the given graph it is a half-circle and a triangle.

So, the diameter of the circle is 6.2 so the radius is 3.1

`\text{Area of a circle}= \pi r^2\\\\\text{Area of a triangle}= (1)/(2) b h\\\\`

Calculating the total area of the shape:

`= \pi r^2+(1)/(2) * b* h\\\\ = 3.14 * 3.1^2+(1)/(2) * 6.2 * 5.6\\\\ = 3.14 * 3.1^2+(1)/(2) * 6.2 * 5.6\\\\=3.14 * 9.61+(1)/(2) * 34.72\\\\=3.14 * 9.61+(1)/(2) * 34.72\\\\= 30.1754+17.36\\\\=47.5354\\\\`
