Answer:
Step-by-step explanation:
We need to find about how to calculate the area of a circle.
And match with the given choices. Where given choices are:
Area of a circle is equal to the diameterdiameter
squaredradiusradius squared times diameterheightpiwidth.
I'm not sure what exactly you have typed lol :)
But I can still answer that.
You just need to apply formula of the area of circle which is given by:

Answer:
maximum height reached = 35 feet
and
Step-by-step explanation:
writing linear motion equations
where s is the total displacement, u the initial velocity, t the time travelled, and a is the acceleration.
given u = 48 ft/s, and a = acceleration due to gravity g = -9.8
1 m = 3.28 feet therefore g becomes -9.8×3.28
here negative sigh comes as acceleration due to gravity is in opposite direction of initial velocity.
therefore f(t) becomes
to find max height we should find differentiation of f(t) and equate it to 0
therefore we get 48 = 32.144t
t = 1.49 s
therefore max height f(1.49) = 71.67-36.67 = 35 feet
