The tip of the hand travels the circumference of a circle with radius (r) 9.5 cm every hour;
The formula for circumference of a circle (c) is:
c = πd = 2πr
So, for a circle with radius 9.5, the circumference is:
c = 2π(9.5)
= 19π cm
The tip travels 19π cm every hour, so in a day of 24 hours it will travel:
24 * 19π = 456π cm
(= 1432.566... ⇒ 1432.6 cm)

Answer:
Its a square. if you graph it, you would see.
Step-by-step explanation:
angle 2 = 90 degrees ( because of the red square in the corner it is a right angle)
angle 4 = 180-70 = 110
total = 90 + 110 = 200 degrees
answer is D
