Step-by-step explanation:
Answer:
A = 90.25 pi in^2
Step-by-step explanation:
The circumference is given by
C = 2*pi*r
19pi = 2*pi*r
Divide each side by 2 pi
19pi / 2 pi = 2*pi*r/ 2pi
9.5 = r
The area is given by
A = pi r^2
A = pi ( 9.5)^2
A = 90.25 pi in^2
There are a 100 cm in one meter so 6 m= 600 cm so 30 cm/ 600 cm = 1 cm/ 20cm or 0.05. Convert that into a percentage and you get 5%.
30cm is 5% of 6 m.
