Robert wrote the division problem below what is the quotient? 13÷83.2

The solution is 0.156

Step-by-step explanation:  if we want to do the division 13/83.2 by hand, a good method can transform both numbers into whole numbers.

You can do this by multiplying both denominator and numerator by 10 (the number of zeros must be equal to the number of numbers after the decimal point, in this case, we have only one, so there is one zero).

Now we have the division (13*10)/(83.2*10) = 130/832 which is easier to solve by hand:

130/832 = 0.156

the figures below are made out of circles, semicircles, quarter … find the area and the perimeter of each figure and give your answers as a completely simplified exact value in terms of π (no approximations). remember that we'll also have to cut whatever areas we get in half, since we're only dealing im pretty sure that is the right answer
