LOTS OF POINTS! Find the Perimeter of the figure below, composed of an isosceles trapezoid and one semicircle. Rounded to the nearest tenths place

4π + 33 or 45.6

Step-by-step explanation:

For this question, you need to identify the perimeter of the semicircle and the 3 sides of the trapezoid.

The perimeter of the semicircle would be (this is the equation for a circle divided by two):

(2πr)/2 or (πd)/2

To figure this out, you don't need to know the radius, because you can just use the diameter, in which case if you plug it in you would get:

(8π)/2

→ 4π

Now you would just add the perimeter of the semicircle to the perimeter of the 3 sides of the trapezoid to get:

4π + (10+13+10)

→ 4π + 33

Now all you'd need to do is round 4π to the tenths place to get:

12.6 + 33

→ 45.6

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
