The formula for the surface area of a cylinder is:
Plug in what we know, use 3.14 to approximate for pi(radius is half the diameter, 30/2 = 15):
Simplify:
Subtract 1413 to both sides:
Divide 94.2 to both sides:
So the height is approximately 45 millimeters.
Answer:
Step-by-step explanation:
In an isosceles triangle, the base angles are equal. This also means that two sides of the triangle are equal in length. Since the sum of the angles in a triangle is 180 degrees, it means that the third angle of the given triangle is
180 - (80 + 50) = 50 degrees
Therefore, the base angles of the isosceles triangle are 50 degrees each. For more triangles with these conditions to be drawn, only the lengths of the equal sides can be increased or decreased. This would in turn increase the length of the third side. Therefore, isosceles triangles of the same angles but different sizes can be drawn.
Answer: < - 15/11
Step-by-step explanation:
Count the squares
6 x 3.5
Area = 6 x 3.5
Area = 21
Perimeter = 6 + 6 + 3.5 + 3.5
Perimeter = 19
Answer:
So first blank=6
Second blank=0
Third blank=-5
Fourth blank=6
Step-by-step explanation:
It is a horizontal line so the equation is just going to be
.
So it will be
We are going to do the point-slope form too as I requested.
Point-slope form is .
We have m=0 since you said the slope was 0 and since it said your have a horizontal line (which means the slope slope or m is 0).
You also that it contains the point .
So our line in point-slope form is .
