Hey there! :)
Answer:
V = 3408 units³
Step-by-step explanation:
Given:
r = 12
h = 71
Volume of a cone: V = 1/3 (bh) where b = πr²
Calculate the area of the base:
A = 12²π
A = 144π units²
Plug this into the formula for the volume of a cone:
V = 1/3 (144π · 71)
V = 1/3 (10224)
V = 3408 units³
17.5
5 is the og length. Scale factor is 3.5. So
5(3.5)=17.5

ANSWER
The multiplication, CA is defined, and its dimension is 3×2
EXPLANATION
Matrix A is a 2x3 matrix.
Matrix C is a 3×2 matrix.
The product of the two matrices , CA, is defined if and only if the inner product of their dimension are the same.

The inner products are the same.
Hence the matrix multiplication, CA is defined and its dimension is the outer products.

Answer:
12.3 - 7.9x
Step-by-step explanation:
8.9 - 1.4x + (-6.5) +3.4
12.3 - 1.4x - 6.5=
12.3 - 7.9x
