Question

1: linear equation of the type ax + b = 0 , where a and b are constants and x is the variable and a is not equal to 0 , can have solutions.

a: only one
b: two
c: no
d:ifinity many solutions

2:All regular polygons are

a:only equilateral .

b:only equiangular

c:both equilateral and equiangular

d:none of these

3: 1 m³ is equal to litres
a: 10000
b:1000
c:10
d:1

4:what ia the formula for finding the volume of a hollow cylinder?​

Answer 1

Answer:

1. a: only one

2. c: both equilateral and equiangular

3. b: 1000

4. A hollow cylinder with rotating on an axis that goes through the center of the cylinder, with mass M, internal radius R1, and external radius R2, has a moment of inertia determined by the formula:

I = (1/2) M( R 1 2 + R 2 2)

Note: If you took this formula and set R1 = R2 = R (or, more appropriately, took the mathematical limit as R1 and R2 ​approach a common radius R), you would get the formula for the moment of inertia of a hollow thin-walled cylinder.
