____ [38]

Given :

A circle is inscribed in a square with a side length of 144.

So, radius of circle, r = 144/2 = 72 units.

To Find :

The probability that the point is inside the circle.

Solution :

Area of circle,

$A_c = \pi r^2\\\\A_c = 3.14 \times 72^2\ units^2\\\\A_c = 16277.76 \ units^2$

Area of square,

$A_s = (2r)^2\\\\A_s = ( 2 \times 72)^2\ units^2\\\\A_s = 20736\ units^2$

Now, probability is given by :

$P = \dfrac{A_c}{A_s}\\\\P = \dfrac{16277.76}{20736}\\\\P = 0.785$

Therefore, the probability that the point is inside the circle is 0.785 .

the measure of ∠D is 5 times the measure of ∠E the two angles are supplemanty find the measure of each angle

hammer [34]

Because the angles are supplementary, they add to 180 degrees.

I solved this by dividing $\frac{180}{6}$ which gives me 30 degrees.

multiply 30 by 5 gives you 150.

and 30 + 150 = 180
