72*12 = 2*2*2*2*2*3*3*3 = 2^5*3^3
Answer: 339.29ft^3
Step-by-step explanation:
The formula for a cylinder is πr^2h
In your scenario, r=8 and h=3 so put those into the equation -
π8^2(3) and just solve!
The volume would be 0.9 x 4.2
This means it is 90% smaller
Don't forget to round the nearest tenth place. That's the first decimal, so you answer should only have 2 digits.
Answer: The correct answer is B.
Step-by-step explanation: We are given the cost of restaurant meal of M. Clark is $25.50.
and she has given 20% of the meal's cost as a tip to the waiter.
Step 1: Calculating the amount of tip paid

Total tip paid = $5.1
Step 2: To find the total amount, we add the cost of the meal and the tip paid
Total amount = Cost of the meal + Tip paid
Total amount = $25.50 + $5.10
Total amount paid by Ms. Clark = $30.6
We know that
angle (3x) and angle (9x) are supplementary angles
so
3x+9x=180°------> 12x=180°------> x=180°/12-----> x=15°
angle (9x) and angle (1) are supplementary angles
so
9x+∡1=180---------> 9*15+∡1=180
∡1=180-9*15---------> ∡1=180-135------> ∡1=45°
the answer is
∡1 is 45°
alternative method
angle 1 = angle 3x----------> vertical angles
∡1=3x-----> 3*15-----> 45°
