Question

Hey mates can you please answer this 2 questions with full process please its urgent

Answer 1

Answer:

9)

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. :-)
