The answer is 2 cm
Step 1. Calculate the height of full cylinder (h1 = ?)
Step 2. Calculate the height of cylinder that contains 314 cm³ of water (h2 = ?)
Step 3. Find <span>the difference between the height of the water in the full cylinder and the height when 314 cm³ of water (h1 - h2 = ?)
The volume (V) of the cylinder with radius r and height h is:
V = </span>π * r² * h
So, h = V / (π * r²)
Step 1.
h1 = ?
V1 = 471 cm³
r = 5 cm
π = 3.14
h1 = V1 / (π * r²)
h1 = 471 / (3.14 * 5²)
h1 = 471 / (3.14 * 25)
h1 = 471 / 78.5
h1 = 6 cm
Step 2.
h2 = ?
V2 = 314 cm³
r = 5 cm
π = 3.14
h2 = V2 / (π * r²)
h2 = 314 / (3.14 * 5²)
h2 = 314 / (3.14 * 25)
h2 = 314 / 78.5
h2 = 4 cm
Step 3.
h1 - h2 = 6 - 4 = 2 cm
Answer:
$59
Step-by-step explanation:
There is a discount of $3 on price of shirt and jeans [both]
Shirt (per unit cost):
Before Discount: $12
After Discount: $12 - $3 = $9
Jeans (pair cost):
Before Discount: $19
After Discount: $19 - $3 = $16
Pani wants to buy 3 shirts and 2 pair of jeans. So her cost would be:
59 dollars.
Answer:
y=4
Step-by-step explanation:
The question is asking what is the value of y:
Since all lengths have a dash on them they are all equal :
So 3y = y+8
3y = y + 8
First we subtract y from both sides:
3y-y = y+8-y
2y = 8
Divide both sides by 2:
2y÷2 = 8÷2
y = 4
