Answer:530.9
Solution Steps:
Area of a circle in terms of radius:
Area = π . r2 = 3.14 × 132 = 530.9 square cm.
In terms of diameter:
Area = π . (d/2)2 = 3.14 × (26/2)2 = 3.14 × (13)2 = 530.9 square cm.
In terms of circumference:
Area = C2/(4π) = 81.682/4π = 6671.62/(4 × 3.14) = 6671.62/(12.56) = 530.9 square cm.
Note: for simplicity, some results may be rounded to nearest hundredth and π was rounded to 3.14. See formula details below in this page.
A circle of radius = 13 or diameter = 26 or circunference = 81.68 cm has an area of 530.9 square centimeters which is equal to:
5.309E-8 square kilometers (km²)
0.05309 square meters (m²)
1.312E-5 acres (ac)
5.309E-6 hectares (ha)
2.05E-8 square miles (mi²)
0.0635 square yards (yd²)
0.5715 square feet (ft²)
82.29 square inches (in²)

Answer:
y = -x - 5 or y = -1x -5
Step-by-step explanation:
y - 2 = -1 ( x + 7 )
y - 2 = -1x - 7
add 2 to both sides
y = -1x - 5
<span>NL←→ is tangent to circle M at point N
NL is perpendicular to MN
so

Step-by-step explanation:
This is asking you to recognize the symbols used to designate a point, line segment, ray, angle, line, and plane.
The point is designated by its letter.
A line segment is designated by the letters of its endpoints, with an overline.
A ray is designated by the endpoint and a point on the ray. The endpoint is listed first. The letters have an arrow over them pointing in the direction from the endpoint.
An angle is designated using the symbol ∠. If three letters are used to identify the angle, the middle one is the vertex.
A line is designated using its name, or by the letters of two points on the line. If the letters are used, there may be a double-ended arrow over them.
A plane is designated by 3 non-collinear points, for example, "plane ABC". It may also be designated by the name of the plane.
Answer:
Step-by-step explanation:What is the probability of an event that is impossible? Suppose that a probability is approximated to be zero based on empirical results. Does this mean that the event is impossible?
What is the probability of an event that is impossible?
