A ball is thrown straight up from the top of a building standing at 50 feet with an initial velocity of 65 feet per second. The height of the ball in feet can be
modeled by the following function: h(t) = -16x² + 652 + 50
a. When does the ball reach its maximum height?
[ Select)
b. What is the approximate maximum height reached by the ball?
Select)
c. How long does it take the ball to hit the ground?
[ Select

34.5 cm

step-by-step explanation:

generally for a circular segment of angle, θ° and radius r

arc length

= (θ/360) x circumference

= (θ/360) x 2πr

in our case, θ = 60°, π=3.142 and r = 33 cm

substitute into above formula

arc length

= (60/360) x 2(3.142)( 33) = 34.5 cm
