C because first you would find the circumference of the circle which is pi times diameter, which is 18.84 but since it is a semi-circle you would divide by 2 which is 9.42. Then you do 3+3=6 + the length which is 6 so you get 12. 12+9.42=21.42 and if you round that to the nearest tenth it is 21.42.
Answer:
6
Step-by-step explanation:
60/6 = 10
6/6 = 1
Answer:
7.85 cm
Step-by-step explanation:
The circumference of a circle can be found using the following formula.
![c=\pi d](https://tex.z-dn.net/?f=c%3D%5Cpi%20d)
The diameter is 2.5 centimeters. Therefore, we can substitute 2.5 cm in for d.
![c=\pi *2.5 cm](https://tex.z-dn.net/?f=c%3D%5Cpi%20%2A2.5%20cm)
Now, find the circumference.
- In terms of pi:
![c=\pi *2.5 cm](https://tex.z-dn.net/?f=c%3D%5Cpi%20%2A2.5%20cm)
![c= (2.5)\pi cm](https://tex.z-dn.net/?f=c%3D%20%282.5%29%5Cpi%20%20cm)
![c= 2.5\pi cm](https://tex.z-dn.net/?f=c%3D%202.5%5Cpi%20%20cm)
-Using 3.14 as pi
![c=\pi *2.5 cm](https://tex.z-dn.net/?f=c%3D%5Cpi%20%2A2.5%20cm)
![c=3.14 *2.5 cm](https://tex.z-dn.net/?f=c%3D3.14%20%2A2.5%20cm)
![c=7.85 cm](https://tex.z-dn.net/?f=c%3D7.85%20cm)
-Using 3.14159... as pi
![c=\pi *2.5 cm](https://tex.z-dn.net/?f=c%3D%5Cpi%20%2A2.5%20cm)
![c=7.85398163 cm](https://tex.z-dn.net/?f=c%3D7.85398163%20cm)
Answer:
y = 5x + 12
Step-by-step explanation:
Use the formula: y - y1 = m(x - x1)
Plug in all numbers into your equation: y - 7 = 5(x - -1)
Minus with a minus becomes a positive: y - 7 = 5(x + 1)
Distribute: y - 7 = 5x + 5
Add 7 to both sides: +7 +7
Answer: y = 5x + 12
Answer:
95.5
Step-by-step explanation:
you can using toa
tan = opp/adj
tan 37° = 72/x
x = 72/ tan 37°
x = 95.547 feet
x = 95.5
