Answer:
A
Step-by-step explanation:
horizontal component=18cos 36.9°≈14.39 m/s≈14.4 m/s
Vertical component=18 sin 36.9°≈10.81 m/s≈10.8 m/s
Answer:
N=48
Step-by-step explanation:

576 is a perfect square
Answer:
<h2>A = 36π yd² ≈ 113.04 yd²</h2><h2>C = 12π yd ≈ 37.68 yd</h2>
Step-by-step explanation:
The formula of an area of a circle:
![A=\pi r^2](https://tex.z-dn.net/?f=A%3D%5Cpi%20r%5E2)
The formula of a circumference of a circle:
![C=2\pi r](https://tex.z-dn.net/?f=C%3D2%5Cpi%20r)
<em>r</em><em> - radius</em>
<em />
We have <em>r = 6yd</em>.
Substitute:
![A=\pi(6^2)=36\pi\ yd^2](https://tex.z-dn.net/?f=A%3D%5Cpi%286%5E2%29%3D36%5Cpi%5C%20yd%5E2)
![C=2\pi(6)=12\pi\ yd](https://tex.z-dn.net/?f=C%3D2%5Cpi%286%29%3D12%5Cpi%5C%20yd)
If you want round the answers, then use <em>π ≈ 3.14</em>
![A\approx(36)(3.14)=113.04\ yd^2](https://tex.z-dn.net/?f=A%5Capprox%2836%29%283.14%29%3D113.04%5C%20yd%5E2)
![C\approx(12)(3.14)=37.68\ yd](https://tex.z-dn.net/?f=C%5Capprox%2812%29%283.14%29%3D37.68%5C%20yd)
