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!

Hope this helps you!!
Answer:
Upstream 1.1 hours and down stream 0.6875 hours.
Step-by-step explanation:
Jen motorboat travels at a speed of 13 mph in still water.
Now, the speed of river flows is 3 mph.
Therefore, the upstream speed of the boat is (13 - 3) = 10 mph and the downstream speed of the boat will be (13 + 3) = 16 mph.
Therefore, to travel 11 miles upstream Jen will take 
hours.
And to travel 11 miles down stream Jen will take 
hours. (Answer)
