There are two different size spherical paintballs and the smaller one has a diameter of 5 cm and the larger one is 9 cm in diameter. if the smaller paintball holds 28 cm3 of paint, how much does the larger one hold?

145.8 cm³ of paint

Explanation:

d₁ = Smaller diameter paintball = 5 cm

d₂ = Larger diameter paintball = 9 cm

V₂ = Volume of larger diameter paintball

Volume of smaller diameter paintball

Similarly

Dividing the above two equations, we get

∴ The larger one hold 163.296 cm³ of paint

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.
