Answer:

The perimeter of a semicircle includes the arc and the diameter. Here are some formulas that you can use.

Step-by-step explanation:

   P = C / 2 + d

       where C is the circumference of the whole circle

   P = π r + 2r

       where r is the radius

       P = (2 + π) r

   P = (d π / 2) + d

       P = d π / 2 + 2 d / 2

       P = (d π + 2 d) / 2

       P = (2 + π) d / 2

5x-3y when x=7 and y=-8
I am Lyosha [343]
5 (7) - 3 (-8)

35 - -24

Because two negatives equal a positive the subtraction sign will change into an addition sign.

35+24

So your answer will be 59.

Hope this helped :)

Find the area of one side, which is length x width:

2/3 x 2/3 = 4/9 square ft.

There are 6 sides to the prism, so multiply the area of one side by 6:

4/9 x 6 = 24/9 = 2 6/9 = 2 2/3 square ft.
