Answer:

93.5 square units

Step-by-step explanation:

Diameter of the Circle = 12 Units

Therefore:

Radius of the Circle = 12/2 =6 Units

Since the hexagon is regular, it consists of 6 equilateral triangles of side length 6 units.

Area of the Hexagon = 6 X Area of one equilateral triangle

Area of an equilateral triangle of side length s = $\dfrac{\sqrt{3} }{4}s^2$

Side Length, s=6 Units

$\text{Therefore, the area of one equilateral triangle =}\dfrac{\sqrt{3} }{4}\times 6^2\\\\=9\sqrt{3} $ square units$

Area of the Hexagon

$= 6 X 9\sqrt{3} \\=93.5$ square units (to the nearest tenth)$

The tens digit of a certain number is five more than the units digit. The sum of the digits is 9. Find the number.

Leokris [45]

the tens digit = n
the units digit = n-5

n + n-5 = 9
2n = 9+5
2n = 14
n = 7 ← the tens digit

the units digit = n-5 = 7 - 5 = 2

the number is 72
