Answer:
Area is = to 1017.88
Circumference is = to 113.1
Step-by-step explanation:
To find the area of a circle use the formula A=πr2
So . . .
A = π18²
A = π324
A = 1017.88
To find the circumfrence of a circle use formula C=2πr
So . . .
C = 2π18
C= 113.1

Answer:
circumference=
D
19.5=3.14*D
<u>19.5</u> =6
3.14
D=6
Radius=3
area=
r²
3.14*3*3=28.26
area=28 inches
Step-by-step explanation:
The answer would be A. Hope this helped! :)
