Answer:the mean is 90
Step-by-step
you find the sum of the values then divide them by the amount of numbers in the set
Answer:
Option A 
Step-by-step explanation:
The volume of a cone is:

The volume of a cylinder is:

Both figures have the same height h and the same radius r.
The volume of the cylinder
We want to find the volume of the cone.
Then, we find r and h:

We simplify.

Then the product of
.
We substitute this in the cone formula and get:

x = 58°
<u>Explanation:</u>
According to the diagram, lines HI and JK are parallel to each other.
∠AHI = 60°
∠JKI = 62°
∠JKI and ∠HIA are equal because when two lines are parallel then the corresponding angles are equal.
So,
∠JKI = ∠HIA = 62°
In ΔHIA,
∠AHI + ∠HIA + ∠IAH = 180°
60° + 62°+ x = 180°
122° + x = 180°
x = 180° - 122°
x = 58°
C
Because 1 km is 1,000 meters so you were just multiply 1000 by 10 and get 10,000
