With 10 to the power to a negative number, it's easier. Here's a trick: The negative number is the places to the right of the decimal. The last number is a 1, while the rest are 0s.
From this, we get:
10^4 = 10000 (four zeros at the end) 10^-4 = 0.0001 (four zeros at the front)
how do u calculate the distance from the centre of the circle to the centre of one edge of the hexagon
Answers
check the picture below.
bearing in mind that a circle has a total of 360°, and a radius line coming from the center of the hexagon, will make an angle of 360°/6 or 60° for each side with the center of the circle, as you see in the picture.
if we run a bisector line through one of those 6 angles, we end up splitting it in two equal halves, namely two 30°, so that the apothem and the radius both coming from the center, with the side, make a 30-60-90 triangle, as you see there.

It cost $520 to plant 4 acres of corn. How much would it cost to plant 3/5 acre of corn?
Answers
Importance should be given to all the informations that are already given in the question. based on those information's, the answer to the question can be easily determined. The cost of planting 4 acres of corn = 520 dollars Then the cost of planting 1 acre of corn = (520/4) dollars = 130 dollars So The cost of planting 3/5 acres of corn = (3/5) * 130 dollars = 3 * 26 dollars = 78 dollars So the cost of planting 3/5 acre of corn is $78. I hope the procedure is clear enough for you to understand. You can always use this method in future for solving similar type of problems without requiring any help from outside.
