A wire 390 in. long is cut into two pieces. One piece is formed into a square and the other into a circle. If the two figures ha
jeka57 [31]

Answer:

Step-by-step explanation:

Let x is the length of the square side.

We know: the two figures have the same area

<=> x^{2} = πr^{2} (r being radius)

<=> x = \sqrt{II} r

perimeter square = 4x = 4*r*\sqrt{II}

perimeter circle = 2*r*π

<=> 390 = 4*r*\sqrt{II}  + 2*r*π

<=> r = 29.16

=> perimeter square =  4*29.16*π

=> perimeter circle = 58.32π

Identify the area of the figure rounded to the nearest tenth. HELP?!! I don't understand!! Please help and show your work!!
Alex73 [517]

Answer:

67.5\ cm^{2}

Step-by-step explanation:

we know that

The area of the figure is equal to the area of rectangle (figure 1) plus the area of trapezoid (figure 2)

see the attached figure to better understand the problem

The area of the rectangle is

A=15*3=45\ cm^{2}

The area of the trapezoid is

A=\frac{1}{2}[(15-9)+3)](8-3)

A=\frac{1}{2}[6+3)](5)=22.5\ cm^{2}

The area of the figure is

45\ cm^{2}+22.5\ cm^{2}=67.5\ cm^{2}
