Yes, your answers are correct.
The volume of a cone is given by V = 1/3πr²h. Since the diameter of the first cone is 4, the radius is 2; therefore the volume is
V = 1/3π(2²)(8) = 32π/3
We divide the volume of the sink, 2000π/3, by the volume of the cone:
2000π/3 ÷ 32π/3 = 2000π/3 × 3/32π = 6000π/96π = 62.5 ≈ 63.
The diameter of the second conical cup is 8, so the radius is 4. The volume then is:
V = 1/3π(4²)(8) = 128π/3
Dividing the volume of the sink, 2000π/3, by 128π/3:
2000π/3 ÷ 128π/3 = 2000π/3 × 3/128π = 6000π/384π = 15.625 ≈ 16
It’s B
Good luck!! Hope this helps
Given:
Equation of a circle
Required:
Find the center and radius of the circle. Then graph of circle.
Explanation:
We have a standard equation of circle
Whose radius is (h, k) and radius r.
We have equation of a circle
Now, we will compare with standard equation of a circle
Graph of circle is
Answer:
Hence, this is the answer.
The nearest tenth means 1 decimal place.
so the answer is 8.5
Wouldn’t the answer be 23?
