Find the area of this figure. Round your answer to the nearest hundredth. Use 3.14 to approximate Pi.
taurus [48]

Answer:

 26.13ft^2

Step-by-step explanation:

Step  1 - As both triangles have lengths the same size, they both add together to equal a rectangle. Therefore:

4 x 3 = 12

Which is the area of the triangles.

Step 2 - Calculating the area of a circle uses the formula:

\pi r^2

Where r is the radius of the circle.

Plug the known variables in:

\pi \cdot 3^2\\\pi \cdot 9\\3.14 \cdot 9 = 28.26\\

However, this is the area of a full circle. The figure is only half a circle so we must divide this by two:

28.26 ÷ 2 = 14.13

Now, add the area of the semi-circle to the area of the triangles:

14.13 + 12 = 26.13

Therefore, the area of the figure is 26.13ft^2.

Hope this helps!

How do I solve this? It says find the value of x, then find the angle measures of the polygon.
Anni [7]
180 = 65 + (x-5) + x
-65     -65

115 = x - 5 + x

115 = 2x - 5

2x = 120

x = 60

The angle measures are 65, 60, and 55 degrees.

Which answer shows this equation written in standard form?
STatiana [176]
4-3(x-y)=-8x+2
=4-3x-3y=-8x+2
=4-3x+8x-3y-2
=5x-3y+2
or 
5x-3y=-2
so it will be C=5x+3y=-2
