Find the determinant of the following matrix. [2 3] [1. 4]

5

Step-by-step explanation:

[2 3]

[1 4]

The determinant of the above matrix can be obtained as follow :

|2 3|

|1 4|

= (2×4) – (1×3)

= 8 – 3

= 5

Thus, the determinant of the metrix is 5

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer
