Answer:
So dimension of rectangle are :
Length = 32
Width = 40
Step-by-step explanation:
Let the length of rectangle be 4x and width of rectangle be 5x.
Remember ratio of length and width is 4 to 5.
Perimeter of rectangle is given as 144.
i.e 2 (length +width) = 144
or 2 ( 4x + 5x ) = 144
Solving this for x, we get :
or 9x = 144/2
or 9x = 72
or x = 72/9
or x = 8
So dimension of rectangle are :
Length = 4 x = 4*8 = 32
Width = 5x = 5*8 = 40
You would take the answer of the square root problem and find the number that you can multiply by its self that would make that answer correct.
Answer:
diameter = 2 * radius = 2 * 14 = 28 cm
Answer:
If 50.24cm = Circumference
Radius = 8cm
If 50.24cm^2 = Area
Radius = 4cm
Step-by-step explanation:
50.24cm what? Circumference? Area?
π = 3.14
2πr = Circumference
50.24 / 2π = r
r = 8
πr^2 = Area
50.24 / π = r^2
r^2 = 16
r = 4
