Answer:
14° I think sorry if its wrong this was quick one
Answer:
Step-by-step explanation:
Radius =6 ft
Area of circle = πr²
= 3.14 * 6 * 6
= 113.04 ft²
base = 10.39 ft
height = 6+3 = 9 ft
![Area \ of \ triangle = \dfrac{1}{2}*base * height\\\\\\=\dfrac{1}{2}*10.39*9\\](https://tex.z-dn.net/?f=Area%20%5C%20of%20%5C%20triangle%20%3D%20%5Cdfrac%7B1%7D%7B2%7D%2Abase%20%2A%20height%5C%5C%5C%5C%5C%5C%3D%5Cdfrac%7B1%7D%7B2%7D%2A10.39%2A9%5C%5C)
= 46.76 ft²
Area of the shaded region = area of circle - area of triangle
= 113.04 - 46.76
= 66.28
= 66.3 ft²
Answer:
900
Step-by-step explanation
That would be 3 * 300 = 900
Answer:
The shorter base is 3
Step-by-step explanation:
![a = \frac{(b1 + b2)}{2} \times h](https://tex.z-dn.net/?f=a%20%3D%20%20%5Cfrac%7B%28b1%20%2B%20b2%29%7D%7B2%7D%20%20%5Ctimes%20h)
![52 = \frac{(10 + b2)}{2} \times 8](https://tex.z-dn.net/?f=52%20%3D%20%20%5Cfrac%7B%2810%20%2B%20b2%29%7D%7B2%7D%20%20%5Ctimes%208)
![b2 = 3](https://tex.z-dn.net/?f=b2%20%3D%203)
Answer:
h(t) = -16t2 + 144
h(1) = -16(12) + 144 = 128 ft
h(2) = -16(22) + 144 = 80 ft
h(2) - h(1) = 80 - 128 = -48 ft
It fell 48 ft between t = 1 and t = 2 seconds.
It reaches the ground when h(t) = 0
0 = -16t2 + 144
t = √(144/16) s = 3s
It reaches the ground 3s after being dropped.
