Step-by-step explanation:
You can find the perimeter of a circle by using the radius.
circumference = 2

Circumference = 2

circumference = 24 pi
Since you are only trying to find half of the circle you would divide your answer by 2
24pi / 2 = 12 pi
12 pi = 37.68
The answer is B. 37.7
A = bh
60 in.² = b(4)
60/4 = b
b = 15 inches
Hope this helped!
It is 30-88 degrees I think
= xy√y +2xy^2√x+ xy<span>√y
= </span> 2xy√y + 2xy^2√x
answer is B. second choice
2xy√y + 2xy^2√x
