Sarah kicked a soccer ball into the air with an initial upward velocity of 48 feet per second. The height (h) in feet of the ball above the ground can be modeled by
h= -16t^2 + 48t, where t is the time in seconds after Sarah kicked the ball.

a. How long was the ball in the air before it returned to the ground?

b. Find the height of the ball after 2 seconds.

Circle a has a diameter of 7 inches, a circumference of 21.98 inches, and an area of 38.465 square inches. the diameter of circle b is 6 inches, the circumference is 18.84 inches, and the area is 28.26 square inches. part a: using the formula for circumference, solve for the value of pi for each circle. (4 points) part b: use the formula for area and solve for the value of pi for each circle. (4 points)
