Answer:
The volume is 2224.96632 or 2224.97(if rounded)
Step-by-step explanation:
First of all, I divided the diameter by two to find the radius:
16.2/2=8.1
Then I used the formula:
V =4/3 πr³
I hope this helps
Each of the triangles are equal in base length, height, and area. Remember the formula for the area of a triangle. The area of any triangle is 1/2 times the length of the base (which, in the polygon, is the length of a side) multiplied by the height (which is the same as the apothem in regular polygon).
Answer:
Step-by-step explanation:
The equation of the circle has the following form
The equation of the circle has the following form
We know that the circle goes through the following points
(1, 7)
(8, 6)
(7, -1).
Then we substitute the values of x and y in the equation
<u>For (1, 7)</u>
(1)
<u>For (8, 6)</u>
(2)
With these equations is enough to solve the system
(1)
(2)
Multiply the equation (1) by -8 and add it to the equation (2)
(1)
(2)
-----------------------------------------------------
Then
Finally the equation is:
Answer:
I believe it's $1,040.
Step-by-step explanation:
So, the original price is $1,300. If we subtract $1,300 by 20% the result should be $1,040.
Therefore, the discounted of the price would be $1,040.
