Answer:
The value of a=4
Step-by-step explanation:
Given the matrix

- A matrix is singular if its determinent is zero.
so solving the matrix B by taking its determinant to get the value a

as according to determinant formula


Therefore, the value of a=4
Answer:
monomial—A polynomial with exactly one term.
binomial— A polynomial with exactly two terms.
trinomial—A polynomial with exactly three terms.
Notice the roots: poly– means many.
Step-by-step explanation:
Hope it helps!!
Using formula A=4πr2
A=π⅓(6V)⅔=π⅓·(6·288)⅔≈210.90123
So area is apprix 210.9
