Answer:
The area of the hubcap is 196π or 615.7521601
Step-by-step explanation:
You can use A=πr² to find the area of a circle. So that would mean that A equals 14². 14²=196. If the answer is in π form, then the answer is 196π. If not then its 196·π. 196·π=615.7521601
Hope that helps!
Answer: 14 - 5 x 5 = -11, and 4 - 3 x 5 = -11.
Step-by-step explanation:
what i did here was just plug in some numbers until the equations reached the same solution. there are probably better ways to do this but i hope this helps anyway.
Answer:
k<±36
Step-by-step explanation:
Δ<0 (no real roots)
b²-4ac<0
k²-4x12x27<0
k²-1296<0
k²<1296
k<±36
Tbh i think its true not 100%
