A=pi r^2
= 20.25 pi is the answer
The answer would be 3mph because 3/4 / 1/4 = 3. So the answer would be 3mph.
Answer:
No
Step-by-step explanation:
An irrational number is a number that never ends or repeats. This decimal ends and it doesn't repeat.
Big/small=4/7
r1/r2=4/7 where r1, r2 are radius of a big and small circles respectively
r1/3=4/7
r1=12/7
circumference of a big circle is2πr1=2π*12/7=24π/7 cm
I believe the answer is x = 3.5. may be wrong though
