Answer:
Surface area of Torrid Zone (cylinder shape) = 80,897,143 miles² (Approx)
Step-by-step explanation:
Given:
Radius of the Earth = 3,960 miles
Find:
Surface area of Torrid Zone (cylinder shape) = ?
Computation:
We know that, distance between two tropics is 3,250 miles.
So, Height = 3,250 miles

Surface area of Torrid Zone (cylinder shape) = 80,897,143 miles² (Approx)
Step-by-step explanation:
A and B works because both are 8x+4y

Answer: Option 'c' is correct.
Step-by-step explanation:
Since we have given that
Sample size = 865 = n
Number of voters favor approval of an issue before the legislature = 408 = x
So, 
At 95% confidence level of significance, z = 1.96
So, confidence interval would be

Hence, option 'c' is correct.
If it is an odd number root of any negative number, the answer will be negative.
From this you can see that -5 x -5 x -5 = -125, so the asnwer is -5.
Answer:

Step-by-step explanation:
I believe you wanted to type that the volume of a cylinder is 40 cubic feet, and try to find what the volume of the same base and height would be in comparison.
Recall that the volume of a cylinder of base B and height H is given by the formula:

Recall as well that the volume of a cone of base B and height H is given by the formula: 
Therefore, if the cone has the same base (B) as the cylinder, and equal height (H), then we can say that the volume of the cone is "one third" of the volume of the cylinder, which in Math terms is written as:

Therefore, in our case, given that the volume of the cylinder is 40
, the volume of the cone would be:
