Find the area and the perimeter of the figure. Use in terms of pi. (no approximations)

See below.

Step-by-step explanation:

So first, we can separate the entire figure into a semi-circle and an isosceles triangle.

AREA:

The area for a semi-circle is .

The diameter is 8cm, so the radius is 4cm.

Area of the semi-circle is:

The area for a triangle is .

The base is the same as the diameter (8), and we are given the height as 10. Thus:

The total area is

PERIMETER:

The perimeter of a semicircle is: (this is derived from dividing the circumference by 2 and then adding on the diameter).

Thus, the perimeter is:

However, we ignore the 8 since the 8 is not part of the perimeter.

The perimeter of the triangle is the two slant lengths. We know the base and the height, so we can use the Pythagorean Theorem:

Two of them will be

Thus, the total perimeter is

not enough information

step-by-step explanation:

we cannot know this, because the other students could have handed out 10 flyers, or they could have handed out 100. one way, the mean would go up, and another way, the mean would go down.

answer: yes i agree that you should not put it on/p>

step-by-step explanation: the reason for this is that it wastes other peoples time and also make them fail as well and that is never good.
