Answer:
136.5picm^2
Explanation:
The surface area of the cylinder is expressed as;
r is the radius
h is the height
Given that;
height h = 16cm
diameter = 7cm
radius = 7/2 = 3.5cm
Substitute the given values into the formula;
Hence the total surface area of the cylinder is 136.5picm^2
To add or subtract radicals, the indices and what is inside the radical (called the radicand) must be exactly the same. If the indices and radicands are the same, then add or subtract the terms in front of each like radical.
Answer:
6.2
Step-by-step explanation:
You can find the median by adding up all of the numbers and dividing the result by how many numbers there are.
add them all together: 5 + 6 +5+6+9 = 31
there are five people, so divided 31 by 5
31 divided by 5 = 6.2

Answer:
Step-by-step explanation:
By definition, the sum of the interior angles of a triangle is 180 degrees.
You can observe that the given triangle has an angle that measures 90 degrees and it also has two equal sides.This means that the other two angles are equal.
Knowing this, you can conclude that the triangle is an Isosceles Right Triangle and the other angles measure 45 degrees each.
Therefore, now you know that:
Solving for "x", you get that its value is:
And for the other angle:
Solving for "y", you get that its value is the following:
the board would be 4.85 feet
