The 'difference' of something tells you that you need to subtract two numbers.
4.6 cm - 3.9 cm = 0.7cm

Because there are 10mm in a cm, you have to times 0.7cm by 10 to get the number of mm.

Therefore, 0.7cm times 10 = 70mm

Find the area of a regular hexagon if given a side length of 1.9 to the square root of 3.

dalvyx [7]

Answer:

28.137 sq. units.

Step-by-step explanation:

Area of a regular hexagon is

$A=\dfrac{3\sqrt{3}}{2}a^2$

where, a is the side length.

It is given that the side length of the regular hexagon is $1.9\sqrt{3}$ .

Substitute $a=1.9\sqrt{3}$ in the above formula.

$A=\dfrac{3\sqrt{3}}{2}(1.9\sqrt{3})^2$

$A=(1.5\sqrt{3})(10.83)$

$A=16.245\sqrt{3}$

$A=28.137$

Therefore, the area of regular hexagon is 28.137 sq. units.

Why is 1/2 of 2 equals one whole

algol [13]

Hey There :)

This is because one is half of two. You could also multiply 2 * 0.5= 1, 0.5 represents $\frac{1}{2}$ and two is the whole number. This is how $\frac{1}{2}$ of two equals one.
