when multiplying scientific notation all you' do is move the decimal whatever times the exponent says or the little number on the 10. Move it to the right when its positive and when its negative move it to the left . I hope that helped :)
Shaded raea = area of circle - area of hexagon
area of circle = pi r^2 = 36pi
area of hexagon = 3 sqrt3 * a^2 / 2 where a = length of each side
To find a:-
consider the triangle with vertex angle = 60 and 2 sides enclosed by 2 sides of length 6 this is an equilateral triangle so a = 6
so, area of hexagon = 3*sqrt3* 6^2 / 2 = 93.531 cm^2
Area of shaded region = 36 pi - 93.531 cm^2
= 19.57 cm^2
Answer:
Substitution rule is one of the most important rule to solve the integrals problem.
In substitution rule we substitute different variable in such a way that it can simplify the question.
example: when we have to solve "Sin x²" we cannot solve it but
if question is "x Sin x²" we can substitute x² with t and can solve it.
The purpose of substitution rule is to simplify the problem of integrals.
1,995,298 rounded to the nearest ten thousand is 1,960,000.
16 cm.
This is because one side of the hexagon is half of one side of the square. Therefore, you multiply 8 by 2. 8x2 = 16
