Answer & Step-by-step explanation:
![Circumference=d\pi \\Area=r^2\pi](https://tex.z-dn.net/?f=Circumference%3Dd%5Cpi%20%5C%5CArea%3Dr%5E2%5Cpi)
The diameter of the circle is 8 m and the radius of the circle is 4 units. So, now we have to plug in the numbers so we can find the circumference and the area of the circle.
![Circumference=(8)\pi](https://tex.z-dn.net/?f=Circumference%3D%288%29%5Cpi)
![Circumference=25.12](https://tex.z-dn.net/?f=Circumference%3D25.12)
So, the circumference of the circle is 25.12 m.
![Area=(4)^2\pi](https://tex.z-dn.net/?f=Area%3D%284%29%5E2%5Cpi)
![Area=16\pi](https://tex.z-dn.net/?f=Area%3D16%5Cpi)
![Area=50.24](https://tex.z-dn.net/?f=Area%3D50.24)
So, the area of the circle is 50.24 units².
Answer:
fff
Step-by-step explanation:
By pythagorean theorum we calculate the height:
![\sqrt{5^2-1^2}](https://tex.z-dn.net/?f=%5Csqrt%7B5%5E2-1%5E2%7D)
=
= height of triangle
area of triangle = base * height
area = ![2*\sqrt{24}](https://tex.z-dn.net/?f=2%2A%5Csqrt%7B24%7D)
There are two triangles so:
![2*2*\sqrt{24}=4\sqrt{24}](https://tex.z-dn.net/?f=2%2A2%2A%5Csqrt%7B24%7D%3D4%5Csqrt%7B24%7D)
Multiply this by 13.25 to get total cost:
=$259.65
