Answer:
x = 5
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 9² = 16²
x² + 81 = 256 ( subtract 81 from both sides )
x² = 175 ( take the square root of both sides )
x = = 5 ≈ 13.23 units ( to 2 dec. places )
Area of a square:
To find the length of a square if you know the area, simply use:
So, we can find the square root of 576 to find the length of the square.
(This is your answer.)
8 x 4 -2 x4 so you do 8x4 and get 32 then you do 2x4 and get 8. 32-8 is 24
Circumference = diameter * pi
diameter = 15 in
circumference = 15pi
