Answer:
19.42 ft.
Step-by-step explanation:
The diameter of the semicircle is 6, so 3.14 x 6 = 18.84. Since it is a semicircle, we divide that by 2 to get 9.42.
The hypotenuse of the right triangles only matter for the perimeter. 5 + 5 = 10, and 9.42 + 10 = 19.42 ft.
Answer:
9 cups of milk is used
Step-by-step explanation:
1/2 + 1/2 + 1/2 = 1 1/2
3×3 = 9
1 piece of pipe ⇒ 3/4 feet
How many pieces? = 27 feet
27 × 1 ÷ 3/4 = 27 × 4/3 = 36 pieces.
Answer Perimeter = 33in
Step-by-step explanation:
AC = 20
BD = 20
AB = 13
O is the midpoint
OD = OC = 20/2 = 10
AB = DC = 13 in
P = DC + OD + OC = 13+10+10 = 33in
