Answer:
r = 5 inches
Step-by-step explanation:
Area of circle, 
It is required to find the radius of the circle. The area of a circle is given by the formula :

r is radius of the circle

So, the radius of the circle is 5 inches.
Step-by-step explanation:
the inner top vertex angle seems to be 90°, so x = 90° too. all angles around a single point in one side of a line are in total 180°.
also, remember, all angles inside a triangle always sum up to 180°.
so, the third inner angle of the triangle is
180 - 90 - 40 = 50°.
that makes z = 180 - 50 = 130°
and y = 180 - 40 = 140°.
Answer:
C) 0 <\ x OR x />7
Step-by-step explanation:
The first arrow has a closed circle which indicates greater/less than or equal to. All the values shaded are to the left of 0. So, <em>x</em> is less than or equal to 0. The second arrow also has a closed circle. Since the shaded part of the arrow is to the right of 7, <em>x</em> is greater than or equal to 7.
