Step-by-step explanation:
Answer:
t is approximately 10.41 seconds
Step-by-step explanation:
s = 16t^2
1734 = 16t^2
divide by 16
1734/16 = 16t^2/16
1734/16 = t^2
take the square root of each side
sqrt(1734/16) = sqrt(t^2)
we only take the positive square root because time must be positive
sqrt(1734/16) = t
t is approximately 10.41 seconds
The measure of the central angle is 89.95 degree or 1.57 radians if the radius of the circle is 7 cm.
<h3>What is a circle?</h3>
It is described as a set of points, where each point is at the same distance from a fixed point (called the centre of a circle)
We have a length of an arc of a circle of radius 7 is approximately 10.99 cm.
The radius r = 7 cm
The arc length l = 10.99 cm
We know,
l = rθ
θ is the central angle.
θ = l/r = 10.99/7 = 1.57 radians
To convert 1.57 radians into the degree multiply it by 180/π
θ = 89.95 degree
Thus, the measure of the central angle is 89.95 degree or 1.57 radians if the radius of the circle is 7 cm.
