Answer:
20.28 cm²
Step-by-step explanation:
The rectangle on the bottom is 7 cm by 2 cm.
The semicircle has a diameter of 7 cm - 1 cm - 2 cm = 4 cm
diameter = 4 cm
radius = diameter/2 = 2 cm
total area = area of semicircle + area of rectangle
total area = (1/2)πr² + LW
total area = (1/2)(3.14)(2 cm)(2 cm) + 7 cm × 2 cm
total area = 20.28 cm²

Step-by-step explanation:
Your full question can be found in the image below
We can easily solve this question by using a graphing tool or calculator to plot the equation
f(x)=-5x^2 +200
See second attached picture
The ball is 50 meters from the ground when
50 =-5x^2 +200
-150 =-5x^2
x^2 = 30
x = 5.477 s
