Answer:
284/3 πx³
Step-by-step explanation:
Volume of a cylinder is expressed as shown:
V = πr²h
r is the radius of the cylinder
r = diameter/2
r = 8x/2
r = 4x
Height of the cylinder = 6x
Volume of the roll with out the hole
V = π(4x)²(6x)
V = 16x²π(6x)
V = 96πx³
The hole in the middle will be a solid sphere with diameter 2x (radius will be x)
Volume of the hole = 4/3πr³
Volume if the hole = 4/3πx³
Volume of the toilet paper roll = volume of the roll without a hole - volume of the hole
= 96πx³ - 4/3πx³
= (96-4/3)πx³
= 284/3 πx³
Step-by-step explanation:
By Sine Rule,
x/sin42° = 37/sin110°.
Hence x = 37sin42°/sin110° = 26.35 in. (A)

Answer:
x = 9
Step-by-step explanation:
-5(1 + 1x) = -50
-5 + -5x = -50
-5 + -5x + 5 = -5x
-50 + 5 = -45
-5x = -45
-5x / -5 = x
-45 / -5 = 9
x = 9
