How was the formula for a sphere originated?
The formula of a sphere, in modern terms, originates from calculus. Given that the area of a circle a(r) = pi*r^2 the definite integration of a(r) from -r to r, the area of the circle rotated around a plane, z, leads to V(r) = definite integral of -r -> r [pi*y^2]dx where r^2 = x^2 + y^2, from the distance formula, so r^2 = x^2 - y^2 V(r) = definite integral of -r -> r [pi(x^2-y^2)]dx V(r) = integral of 0 -> r minus integral of -r -> 0 V(r) = pi(r^3 - (r^3)/3) - pi(-r^3 + (r^3)/3), collect terms V(r) = (2pi*r^3)/3 + (2pi*r^3)/3 V(r) = (4pi*r^3)/3

What is 10 equals r plus 3?
10 = r + 3 Subtract 3 from each side: 7 = r
How To Simplify r22r3 can you please show your work so i can understand how to do this?
1) If it is: (r^22)(r^3) = r^(22 + 3) = r^25 (Just add powers) 2) If it is: (r^2)(2)(r^3) = 2[r^(2 + 3)] = 2r^5
Write a c program of matrix addition to handle two dimensional array?
#include<stdio.h> #include<conio.h> void main() { int a[3][3],b[3][3],c[3][3],r,c; for(r=0;r<=3;r++) { for(c=0;c<3;c++) { printf("\n enter the value="); scanf("%d%d",&a[r][c],&b[r][c]); } } printf("\n first matrix=\n"); for(r=0;r<=3;r++) { for(c=0;c<3;c++) { printf("%d\t",a[r][c]); } printf("\n"); } printf("\n scond matrix=\n"); for(r=0;r<=3;r++) { for(c=0;c<3;c++) {printf("%d\t",b[r][c]); } printf("\n"); } printf("\n sum of given matrix=\n"); for(r=0;r<=3;r++) { for(c=0;c<3;c++) { c[r][c]=a[r][c]+b[r][c]; printf("%d\t",c[r][c]); } printf("\n"); } getch(); }
What is the answer to this math problem r divided by 4 equals 1 divided by 3?
R/4 = 1/3 r/4*4 = 1/3 *4 r=4/3
How would you prove that the surface area of a sphere when divided by its volume is always equal to 3 over its radius giving examples?
Area = 4*pi*radius2 and volume = 4/3*pi*radius3 And: 4*pi*r*r divided by 4/3*pi*r*r*r => 3*4*pi*r*r/4*pi*r*r*r Then by cancelling it becomes: 3/r Check: If radius is 6 then it is 3/6 or 1/2 Check: If radius is 0.5 then it is 3/0.5 or 6 Check: If radius is 11 then it is 3/11
