Find an equation in standard form for the ellipse with the vertical major axis of length 16 and minor axis of length 10.

A. x squared divided by 5 plus y squared divided by 8 = 1
B. x squared divided by 25 plus y squared divided by 64 = 1
C. x squared divided by 8 plus y squared divided by 5 = 1
D. x squared divided by 64 plus y squared divided by 25 = 1

The answer to your question is the letter B.

Step-by-step explanation:

Data

major axis = 16

minor axis = 10

Process

1.- Calculate the value of a

       major axis = 2a = 16

                              a = 16/2

                              a = 8

2.- Calculate the value of b

       minor axis =2b = 10

                              b = 10/2

                              b = 5

3.- Write the equation of a vertical ellipse

 C = (0, 0) and h = 0, k= 0

4.- Write the equation of the ellipse

The right answer is B because the denominators are simplified.

125.60

Step-by-step explanation:

the formula for the area of a cylinder is A=2πRH+2πRsquared. I find it easiest to multiply pi by 2 instead of anything else which is 6.28. Then I multiply the radius (2) times the height (8) equaling 16. Then you multiply that number by 6.28. Equaling 100.48. Then you have to do the second part which is radius (2) squared equaling 4. Then you multiply that by 6.28, equaling 25.12. then you add the two sums (25.12+100.48=125.60).

hope that makes sense!!
