In 1 hr the clock will complete 1rotation.
So, here radius of circle = 15cm circumference of circle = 2πr
circumference of circle = 2×3.14×15 circumference of circle = 2=94.2cm
10)
The length of the wire is the only constant here. That can be changed from circumference of the circle to perimeter of the square.
Length of the wire = circumference of the circle
Length= 2πr=2×3.14×25
Length = 6.28×25
Length= 157 cm
Now, perimeter of square = length of wire
4×side = 157 cm
Side = 157/4
Side = 39.25
Hope they help u. :-)
