c = 2(3.14)(radius)
c = 2(3.14)(3)
<em>multiply all those numbers together to get your circumference.</em>
c = 18.84.
The 2 in 324 represents the number 20 out of 300 and 4. With decimal in front, the 2 now represents hundredths of 1.
Answer:
A: y=-2/3x + 3
B: y=x-2
solution: (3,1)
Step-by-step explanation:
Answer:
The length of KH is 6 units and OH is 6.3 units.
Step-by-step explanation:
Given the figure with lengths LO=5 and OK=4. we have to find the length of OH and KH.
In ΔLOH
By Pythagoras theorem
→ (1)
In ΔKOH,
→ (2)
In ΔKHL,
![KL^2=LH^2+KH^2](https://tex.z-dn.net/?f=KL%5E2%3DLH%5E2%2BKH%5E2)
Using eq (1) and (2), we get
![KL^2=5^2+OH^2+OH^2+4^2](https://tex.z-dn.net/?f=KL%5E2%3D5%5E2%2BOH%5E2%2BOH%5E2%2B4%5E2)
![9^2=25+2OH^2+16](https://tex.z-dn.net/?f=9%5E2%3D25%2B2OH%5E2%2B16)
⇒ ![2OH^2=81-25-16=40](https://tex.z-dn.net/?f=2OH%5E2%3D81-25-16%3D40)
⇒ ![OH=\sqrt{20}=6.324\sim6.3units.](https://tex.z-dn.net/?f=OH%3D%5Csqrt%7B20%7D%3D6.324%5Csim6.3units.)
Put the above value in eq 2, we get
⇒ KH=6 units.
