the answer is 11/7 feet because the perimeter of a circle is πr² and a semi circle is half of a circle then the formula would be 1/2 πr² 1/2×22/7×1 (it is 1 because we have divided the diameter to get radius so we derived at 11/7.
Answer:
∠Y = 104°
Step-by-step explanation:
vertical angles are equal ⇒ ∠DAN = ∠SAY = 48°
Sum of interior angles of a triangle = 180°
⇒ ∠SYA + 56 + 48 = 180
⇒ ∠SYA = 76°
Angles on a straight line add up to 180°
⇒ ∠Y + ∠SYA = 180°
⇒ ∠Y + 76 = 180
⇒ ∠Y = 104°
Answer:
-n⁴ + 4n
Step-by-step explanation:
Step 1: Write expression
(3n⁴ + 6n + 6n) - (n + 4n⁴ + 7n)
Step 2: Combine like terms
3n⁴ + 12n - (4n⁴ + 8n)
Step 3: Distribute -1
3n⁴ + 12n - 4n⁴ - 8n
Step 4: Combine like terms
-n⁴ + 4n
Answer:
<h2>864π in³</h2>
Step-by-step explanation:
Volume of the water is equivalent to the volume of a cylinder = πr²h where;
r is the radius of the cylindrical tank
h is the height of the water
Given parameters
radius of the cylindrical tank r = 1feet = 12 inches
height of the water inside the tank = 6inches
Volume of the water = πr²h
Volume of the water = π(12)²*6
Volume of the water = π*144*6
Volume of the water = 864π in³
<em></em>
<em>Hence the volume of the water is 864π in³</em>
