Question

need by tonight plz help me

Answer 1

Answer:

Step-by-step explanation:

Diameter = 18 m

D= 2*r

r = d/2

r =18/2

r = 9

Circumference = 2 * pi * r

C = 2 * 3.14 * 9

C = 56.52

Area = pi r^2

Area = 3.14 * 9^2

Area = 3.14 * 81

Area = 254.34

Answer 2

Answer:

Radius=9

Circumference= 56.52  or 56.52

Area= I not sure

Step-by-step explanation:

Radius= 18 divided by 2 equals 9

Circumference= 18 times 3.14

I'm sorry if it's wrong, I kinda forgotten about this lesson.
