The width is 2.5 cm long and could not be the right answer
Answer:
Explanation:
It is given that,
Radius of the circle, 
The area of the circle is given by :
or
As there is no uncertainty given in the radius of the circle. So, the area of the circle is 
. Hence, this is the required solution.
The first person went further. s = d/t
Hope this helps you out APHDenmark! :D
The distance traveled by the arrow and horizontal velocity are directly proportional, thus when the distance increases, an increase in initial velocity will allow the arrow to hit the target.
<h3>
Time of motion of the projectile</h3>
If the horizontal distance the projectile would travel before hitting the target is 70.67 m, the time of motion of the projectile is calculated as;
X = Vx(t)
t = X/Vx
t = X/Vcosθ
t = (70.67) / (45 x cos10)
t = 1.6 s
When the archery target is moved further away from the archer, the archer needs increase the initial velocity of the arrow assuming the angle of projection is constant.
Since the distance and horizontal velocity are directly proportional to each other, thus when the distance increases, an increase in initial velocity will allow the arrow to hit the target.
