How do I create a function finding Surface Area, Volume, and Density of a cone?

83 visualizzazioni (ultimi 30 giorni)
I've already created a function, and it reads as follows and gives me wildly incorrect answers. Is there something I'm missing?
function [SA,V,D] = coneProperties(r,m,h)
SA = pi*r*(r+sqrt(h.^2 + r.^2));
V = pi*r^2*(h/3);
D = m./V;
The surface area answer should be about 254, but it gave me 1.337628854861238e+03, which is very much not the right answer. I'm not sure what I've done wrong, so any help is appreciated!

Your formulas look correct to me.
What input values of r, m, and h did you use, to get those expected values?
Are you sure you entered the inputs in the correct order?

You are totally right. I put them in the wrong order. Thank you! Also the variables were as follows
r = 5,
m = 80,
h = 10,

Looks like the OP had it right, but Im adding the formula back here for completeness.
function [SA,V,D] = coneProperties(r,m,h)
SA = pi*r*(r+sqrt(h.^2 + r.^2));
V = pi*r^2*(h/3);
D = m./V;
% Radius r, mass m, height h.
% Surface Area SA, Volume V, Density D.
