Answer:
18.87 square cm.
Step-by-step explanation:
The area of the rectangle will be (4 + 4) * 4, since the length of the rectangle would be the diameter of the circle, and the width of the rectangle would be the radius. (4 + 4) * 4 = 8 * 4 = 32 square cm.
Then, we can calculate the area of the semicircle. The area of a circle is pi * r^2, so the area of a semicircle will be half of that. pi * (4^2) / 2 = pi * 16 / 2 = 8pi. 8 * 3.14159265 = 25.1327412 square cm.
The shaded area of the middle of the shape will then be 32 - 25.1327412 = 6.8672588 square cm.
The two triangles will have the same area. Their bases will be 14 minus the diameter of the circle, then divide that by 2 to get each separate base. 14 - 8 = 6 / 2 = 3. The heights of the triangles will be the radius of the circle, or 4 cm.
1/2 * 3 * 4 = 1/2 * 12 = 12/2 = 6. That is the area of one triangle, so the area of both triangles would be 6 * 2 = 12 square cm.
6.8672588 + 12 = 18.8672588, or 18.87 square cm.
Hope this helps!
area is found by multiplying length by width
so
26.4 times 12.25 =
and the answer is feet squared

Answer:
D) If an integer is NOT even then it is NOT divisible by 2.
Step-by-step explanation:
An inverse if/then statement is like an opposite statement. So the statement "if A happens, then B will happen" the opposite would be like saying "if A does NOT happen then B will NOT happen." Hopefully that makes sense :)
Answer:
<=> 5x = 3y - 8
3y + 10 = 0 or y - 6 = 0
<=> 5x = 3y - 8
y = -10/3 or y = 6
+) with y = -10/3 => 5x = -10 - 8 <=> 5x = -18 <=> x = -3.6
+) with y = 6 => 5x = 3.6 - 10 = 8 <=> x = 8/5 = 1.6
