Answer:

8cm

Step-by-step explanation:

First you must know that the diameter of the semi-circular patio is equal to the length of one side of the square

Area of a semi circle = πr²/2

25.12  = πr²

25.12 = 3.14r²/2

r² = 25.12(2)/3.14

r² = 16

r = √16

r = 4

Get the diameter

d = 2r

d =2(4)

d = 8cm

Hence the length of the side of the square is 8cm

Which is the value of the expression ((10^4)(5^2)/(10^3)(5^3))^3
dimulka [17.4K]

Answer:

8

Step-by-step explanation:

Let's set this up to see if we can simplify it a bit:

(\frac{10^4*5^2}{10^3*5^3})^3

Notice we have 4 tens on top and 3 on bottom, so we can eliminate the bottom 3 altogether and leave just one on top.  And we have 2 fives on the top and 3 on bottom, so we can eliminate the 2 on the top and leave one on the bottom.  Now that looks like this:

(\frac{10}{5})^3

10 divided by 5 is 2, and 2 cubed is 8

What is the area of a triangle with a base length of 2 1/2 inches and a height of 2 inches
Sedaia [141]
Hello I am happy to help you with this problem. So the formula to solve for a triangle is A = bxh divided by 2.
So it’s area equals base times height divided by 2. So the base is 2 1/2 which becomes 5/2 ( five over 2) times 2 which equals 5. It’s because you cancel. So 5 divided by 2 equals 5/2 which also equals 2 1/2.



I hope that helps you. If you have any questions please feel free to ask me.
