Just to make it easy for you, I am making this statements. Simply remember the area of the circle = pi*r^2. Multiply this by another radius quantity so it becomes = pi*r^3. Now just multiply with 4/3 to get the volume of the sphere= 4/2*pi*r^3. To get hemisphere volume just divide by two (Hemisphere...

To get hemisphere volume just divide by two (Hemisphere = half the sphere) so Hemisphere volume=2/3*pi*r^3 ( if you like to know the exact derivation of this quantity you can go through integral calculus). read less

Solve : 141x + 103y = 217; 103x + 141y = 27
First add both equations, we'll get 244x+244y=244, Now, Divide this equation by 244, it gives x+y=1.....(a) Again, subtract equation 2 from 1, it gives 38x-38y=190, Now, divide this equation by 38,comes x-y=5.....(b) Now...

Find the product: (x – 3y) (x + 3y) (x2 + 9y2)
The product of the first two terms is x^2 - 9y^2. The third term is x^2 + 9y^2 So the final product is x^4 - 81y^4
