The radius is found from

... A = πr²

... r = √(A/π) = √(154/π) m ≈ 7.00 m

The circumference is then

... C = 2πr = 2π(7.00 m) ≈ 43.99 m

The circumference is about 44.0 m.

4. The area of a rhombus with one diagonal is 8.72 cm long is the same as the area of a square of side 15.6 cm. Find the length

Lubov Fominskaja [6]

Answer:

55.82 cm

Step-by-step explanation:

d1= 8.72 cm

a= 15.6 cm

A rhombus= 1/2*d1*d2 = A square

A square= 15.6²= 243.36 cm²

d2= 2A/d1= 2*243.36/8.72 ≈55.82 cm

Are angles congruent when their side measures are the same

Mkey [24]

Answer:

I don't believe so because congruent shapes are exactly the same but a side measurement could be the same on a square and a triangle but those aren't congruent shapes

Please help me ASAP?!!

Blababa [14]

Answer:

(0,-5) and (-4,3)

Step-by-step explanation:

The given equations are

$\left \{ {{x^2+y^2=25} \atop {2x+y=-5}} \right.$

Make y the subject in the second equation;

$y=-2x-5$

Substitute into the first equation;

$x^2+(-2x-5)^2=25$

Expand:

$x^2+4x^2+20x+25=25$

$x^2+4x^2+20x+25-25=0$

$5x^2+20x=0$

$5x(x+4)=0$

$\Rightarrow x=0,x=-4$

When x=0,

$y=-2(0)-5=-5$

This gives; (0,-5)

When x=-4

$y=-2(-4)-5=3$

This gives (-4,3)
