Question

Find the area of the irregular figure (use 3.14 for pi) show your work and round to the nearest tenth.

Answer 1

this is the picture to help!!

Answer 2

Can you identify different figures here?

Answer 3

@melissa15 can you see a triangle and semi-circle?

Answer 4

i can see them lol

Answer 5

first find the area of the half of the circle..
\[A = \frac{ 1 }{ 2} \ \pi \ r^{2}\]\[A = \frac{ 1 }{ 2 } \times 3.14 \times (1.8)^2\]\[A = 5.0868\]

here in the diagram the have no given the radius .instead the have given the diameter u can find the radius using the diameter
\[radius =\frac{ diameter }{ 2} = \frac{ 3.6 }{ 2 } = 1.8\]
after that find the area of the triangle..
\[Area\ of \ a \ \triangle = \frac{ 1 }{ 2 } \times base \times height \]
here
height = 4.8
base = 3.6
so..
\[Area= \frac{ 1 }{ 2 } \times 4.8 \times 3.6\]
\[Area = 8.64\]
now..
\[The \ total \ Area = Area \ of \ the \ \triangle + Area\ of \ the \ semi \ circle\]
\[the \ total \ area = 8.64 + 5.0868\]

Answer 6

lol then you know the formula to find area of triangle?
