Answer:
13 cm × 12 cm
Step-by-step explanation:
The diagonal of the top or bottom faces of the box is the hypotenuse of a triangle with legs 12 cm and 5 cm. The Pythagorean theorem tells you that diagonal length is ...
d = √(12² +5²) = √(144 +25) = √169 = 13 . . . cm
The width of the divider is 13 cm.
The height of the divider is shown as 12 cm.
The dimensions of the dividing rectangle are 13 cm by 12 cm.

15.36x[-0.45] = 0
Reorder the terms for easier multiplication:
15.36 * -0.45x = 0
Multiply 15.36 * -0.45
-6.912x = 0
Solving
-6.912x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Divide each side by '-6.912'.
x = 0
Simplifying
x = 0</span>
Y= 1x is the correct answer
Circumference Formula: 2pi x r
Radius = 20.5
Plug it in:
2(3.14) x 20.5
6.28 x 20.5 = 128.74
Then, convert to pi terms.
128.74 = 41 pi
Therefore the circumference of a circle with a radius of 20.5m is 41pi.
