Answer: 80
Step-by-step explanation:
We can use the formula 
, where 
are the lengths of the diagonals.
By the distance formula,
So, the area is 
-20- -10=-10
l10l
I hope it’s correct
The Answer is A
Explanation:
The standard form equation for an ellipse is:
(x - h)² / a² + (y - k)² / b² = 1
So looking at the picture above you can see that the center of the ellipse is at the origin which is (0;0) making both h and k zero.
It is then observed that the x-intercepts are at 12 meaning a=12 and y- intercepts are at approximately square root of 95 which is 9.746... which are 'k'
So you can conclude by saying that:
x²/12² + y²/(sqrt of 95)² = 1
then giving you the answer of A which is:
x²/144 + y²/95 = 1
Answer:
(-1, -7)
Step-by-step explanation:
Used desmos, also, in these situations I believe you can take the number inside the brackets and make it negative and keep the number outside the same to find the vertex.
Answer: The volume would be 61.261.
Step-by-step explanation: To find the volume of a sector of a cylinder use the following formula and fill in the variables with the appropriate data. V = π r² h * Θ / 360°
