What is the surface area of the cone?
goblinko [34]

Answer: C

Step-by-step explanation:

To find the surface area of a cone, you use the formula A=\pi r(r+\sqrt{h^2+r^2} ). Since we are already given the height and radius, all we have to do is plug in the values and solve.

A=9\pi (9+\sqrt{41^2+9^2} )       [solve inside of square root]

A=9\pi (9+\sqrt{1762} )             [parenthesis]

A=9\pi (50.976 )                   [multiply]

A=458

Therefore, the closest answer is C.

This is hard can someone help ?
Anastaziya [24]

6. Often, judging the symmetry and skewness of such distributions is not easy to do by eye, especially when they are asymmetrical or skewed in different ways. Here, the mean of set A is about 7, so the data is skewed to the left more than for set B, which has a mean of about 5.4--closer to the middle of the range.

Both data sets have the same range: 2–10. Set A's mode of 8 is higher than set B's mode of 6.

Hence, the only true statement appears to be

... B. Set B has the lesser mean.
