Answer:
Solution : Volume = 96/5π
Step-by-step explanation:
If we slice at an arbitrary height y, we get a circular disk with radius x, where x = y^(1/3). So the area of a cross section through y should be:
A(y) = πx^2 = π(y^(1/3))^2 = πy^(2/3)
And now since the solid lies between y = 0, and y = 8, it's volume should be:
V = ∫⁸₀ A(y)dy (in other words ∫ A(y)dy on the interval [0 to 8])
=> π ∫⁸₀ y^(2/3)dy
=> π[3/5 * y^(5/3)]⁸₀
=> 3/5π(³√8)⁵
=> 3/5π2^5
=> 96/5π ✓
Answer:
What are the numbers?
Step-by-step explanation:
Answer:
No, Kareem is incorrect.
Step-by-step explanation:
Kareem says that the ratio of 
because 4 + 8 = 12 and 1 + 8 = 9
But the correct way to rewrite the ratio 4 : 1 is,
Which becomes as,
Therefore, Kareem is not correct.
Correct ratio equivalent to 4 : 1 is 12 : 3.
Answer:
32.4kg
Step-by-step explanation:
if it loses one tenth of cement;
36kg×1/10
36kg/10
3.6kg was lost
to find the remaining ; 36kg - 3.6kg = 32.4kg is left in the bag
Answer:
Its D
Step-by-step explanation: Since the answer choices B and C don't make sense, its between A and D.
A is actually wrong since it said that the lower class benefited protection from these lords and serfs. Also, the last two lines support D.
