Answer:
2.5 cm
Step-by-step explanation:
Since they give you the height of the button, it is the same as the diameter. The diameter is 2 as big as the radius so, we need to divide 5 by 2 to get the radius.
<u>Example: The diameter is 6, find the radius</u>
To find the radius, divide 6 by 2
6 / 2
<em>3 is the radius</em>
The Actual Problem:
<u>Step 1: Find the radius by dividing 5 by 2</u>
5 / 2
<em>2.5 cm is the radius</em>
Answer: 2.5 cm
The area is A. 36cm
A=b•h
Therefore, 6•4=24
3•4=12
24+12=36
Hope this helps:))

Answer: 20</h3>
============================================================
Explanation:
It might help to rotate the figure so the parallel sides are horizontal. This is optional.
The parallel bases are and in either order.
The height is h = 4 which is always perpendicular to both bases.
Plug these values into the trapezoid area formula.
The area of the trapezoid is 20 square units.
-----------
Another pathway is to break the trapezoid into a rectangle up top and a triangle down below.
The rectangle is 4 by 4 with area 4*4 = 16
The triangle has a base of 6-4 = 2 and height of 4, so its area is base*height/2 = 2*4/2 = 8/2 = 4
Overall the total area is rectangle+triangle = 16+4 = 20 square units.
If 2 lines are parallel they have the same slope.
the answer is -7
