Answer:
1178.25cm^3
Step-by-step explanation:
Volume of a cylinder is given as V = Pi x r^2 xh
PI= 3.142
R = 5cm
H=15cm
So volume = 3.142 x 5cm x 5cm x 15cm
= 1178.25cm^3
Answer:

Step-by-step explanation:
In the given figure, PQRS is a rhombus and SRM is an equilateral triangle.
We are also given that SN⊥RM and that ∠PRS = 55°.
And we want to find the measure of ∠QSN.
Remember that since PQRS is a rhombus, the angles formed by its diagonals are right angles. Let the intersection point of the diagonals be K. Therefore:

Now, RKS is also a triangle. The interior angles of all triangles must be 180. Thus:

Substitute in known values:

Solve for ∠KSR:

Since SRM is an equilateral triangle, this means that:

Note that RNS is also a triangle. Therefore:

Substitute in known values:

So:

∠QSN is the addition of the two angles:

Therefore:

The only possibility if a number is not even is that it is odd. Thus, the event would be the product is an odd number.
Answer:
1. x = -15
2. x = 0.25 or x = 1/4
Step-by-step explanation:
1.
8 + 9.8x + 9 = 3.8x - 16 + 3.8x
Simplify both sides
17 + 9.8x = 7.6x - 16
-17 -17
9.8x = 7.6x - 33
-7.6x -7.6x
2.2x = -33
Divide by 2.2
x = -15
2.
-2x - 10 = -14x - 7
+7 +7
-2x - 3 = -14x
+2x +2x
-3 = -12x
Divide by -12
0.25 = x
x = 0.25 or x = 1/4
