Answer:
U₂₁ and U₂₂ fits in the line of upper triangular
Step-by-step explanation:
As explain in the question
An upper triangular matric is square matrix with all zeros below its daignal. A lower triangular matrix is a square matrix with all zeros above its diagonal.
(as shown in the attached image)
(a)for all 3×3 upper triangular matirices U, verify that U2 is also upper triangular
for a matrices U (having a 3*3 matrix), assuming for example, U is given below:
U =
the element in the upper triangular are 1,2,3,5,6,9 (U₁₁, U₁₂, U₁₃; , U₂₂, U₂₃, U₂₂)
while lower triangular are 0,0,0, the element in the lower triangular are (U₂₁, U₃₁,U₃₂)
U₂₁ and U₂₂ fits in the line of upper triangular
Answer:
Step-by-step explanation:
Given
Hemisphere
Cone
Required
Determine the radius of the cone
First, we calculate the volume (V1) of the hemisphere.
Substitute 7 for r
Volume (V2) of a cone is:
Because the lead is cast into a cone, then they have the same volume.
So, we have:
Substitute 49 for h
Divide both sides by 49
<em>Hence, the radius of the cone is 3.74cm</em>
