A cube and a rectangle prism both have 8 vertices
All you do is change signs write 2x minus 14 equals negative 10-14 equals four then you write 2x over two equals four over two then u write x equals negative two
45º is 1/8 of a circle.
So, divide 72π by 8 to get the answer.
72π / 8 = 9π
The area of the sector is 9π.
Hope this helps!
