Ellipse - In geometry, an ellipse (from Greek ἔλλειψις elleipsis, a 'falling short') is a plane curve that results from the intersection of a cone by a plane in a way that produces a closed curve. Circles are special cases of ellipses, obtained when the cutting plane is perpendicular..

Question : 1. A quadrant of a circle (radius 4.5m)
2. An ellipse (major axis 6m and aminor axis 4m)
Please tell me how you worked it out.
Answer : 1. The formula for area of a whole circle is: Area = (pi)(radius)^2, where pi is about 3.14. So the area of a quadrant, or 1/4 of a circle is A = (1/4)(pi)(radius)^2. Plugging in 4.5 for r: A = (1/4)(pi)(4.5)^2 A = (1/4)(3.14)(4.5)^2 A = 15.904 meters squared 2. The formula for the area of an ellipse is: A = (pi)(a)(b), where a is the length of the major axis (the longer of the two) and b is the length of the smaller axis. Plugging in a = 6 and b = 4: A = (pi)(6)(4) A = (3.14)(6)(4) A = 75.36 meters squared

Question : I need to find the exact and approximate volume of the ellipse. I guess that means solve explicitly and using FnInt.
The equation for the ellipse is:
(4x^2)/(121) + (y^2)/ (12) = 1
The bounds of the ellipse appear to be from:
-11/2 ------> 11/2
I've tried getting a y= equation but that leaves me with the sqrt of a negative polynomial. Thank you all for your help. This is my last problem and its driving me crazy! *sigh* I found the approximate area to be 29.92769001 when I put ..
Answer : You can graph the top half of the ellipse with y = sqrt (12 - 48x /121) That is a semi-ellipse, so when you find the area using the calculator's integration function with your correct boundaries, you need to multiply the result by 2 (not 2 ) The explicit formula for the area of an ellipse is ab, where a = distance from center to vertex and b is distance from center to co-vertex. In your equation, the area = *(11/2)*(2 3) = 11 3 On edit: I just reread the question and you are asking for both area and volume. Which do you need? Ellipses don't have volume unless you are talking about the volume of the solid formed by a rotation about the x-axis. If that is what you mean, then the integral is from -11/2 to 11/2: [sqrt (12 - 48x /121)] dx = [12 - 48x /121] dx
