Answer:
Step-by-step explanation:
The standard form of an equation of a circle:
(h, k) - center
r - radius
We have the endpoints of the diameter of a circle (-8, -6) and (-4, -14).
The midpoint of a diameter is a center of a circle.
The formula of a midpoint:
Substitute:
We have h = -6 and k = -10.
The radius is the distance between a center and the point on a circumference of a circle.
The formula of a distance between two points:
Substitute (-6, -10) and (-8, -6):
Finally we have
Answer:
301.54 cubic centimeters.
Step-by-step explanation:
Given:
The top of each fence post is a square pyramid.
The side length of the base of the fence top is 10.1 cm.
The height of the fence is 8.868 cm.
Question asked:
What is the volume of the post top ?
Solution:
First of all we will find base area of the fence then volume of post top (square pyramid)
Side length = 10.1 cm
As we know:
Now
Thus, volume of the post top is 301.54 cubic centimeters.
