Mathematics
1 answer:
olga nikolaevna [1]3 years ago
3 0

Answer:

Step-by-step explanation:

C=pi*3           Given

Generally C = 2*pi*r so we need to solve for r

3 pi = 2*pi * r   Divide by 2pi

3 pi/2pi = r

r = 1.5

Area = pi r^2

Area = pi * 1.5^2

Area = 2.25 pi

If you need a 1 number answer

Area = 7.065
