The exact circumference of the circle is
The approximate circumference of the circle is
Explanation:
The diameter of the circle is
Now, we shall find the circumference of the circle.
The formula to determine the circumference of the circle is given by
Where C is the circumference , is 3.14 and
is the diameter of the circle.
The exact circumference of the circle is given by
Multiply both numerator and denominator by 100, we get,
Converting into mixed fraction, we get,
Thus, the exact circumference of the circle is
The approximate value of the circumference can be determined by dividing the value
Thus, the approximate circumference of the circle is
So hmm notice the picture below
the pyramid itself, is really, just one regular hexagon, at the bottom
and 6 triangles, stacked up at each other at the edges
now, if you just get the area of the regular hexagon, and the 6 triangles, add them up, that'd be the total surface area of the pyramid then
now, for the triangles, well, area of a triangle is 1/2 bh, as you'd know, and you have both
