Answer:
A = 90.25pi sq m
OR = 361pi/4 sq m
Step-by-step explanation:
If the circumference is 19pi, then the diameter is 19.
C = pi•d
19pi = pi•d
19 = d
If the diameter is 19, then the radius is 9.5.
The radius is always half of the diameter.
Then we can find the area.
A = pi•r^2
=pi•9.5^2
=90.25pi
We don't often see a decimal number coefficient for pi. So as an improper fraction, 90.25 which is 90 1/4 is
(90×4)+1 over 4
= 361/4
Area = (361/4)pi
=361pi/4 sq meters
