Question

Find the area of the compound figure. Round your answer to 2 decimal places if required. (Use π = 3.14)

Answer 1

Answer:

first you will need to break the shape into a semi circle and a triangle.

then solve the area of the semi circle. which is

$\frac{(3.14) \times r ^{2} }{2}$

$\frac{(3.14) \times 4.6^{2} }{2} \\ = 33.22$

Then solve the area of the triangle.

First work out the height of the triangle, which is

$13.4 - 4.6 = 8.8$

then the area. which is

$\frac{1}{2} 4.6 \times 8.8 \\ = 20.24$

now calc. the two figures. which is

$20.24 + 33.22 \\ = 53.46$
