Answer:
Radius: 18
Area of Circle: 1017 or 1018(depends on whether you used the pi function or 3.14)
Step-by-step explanation:
Formula for the circumference and area:
C= 2πr
A= πr^2
radius is 17.99 area is 1016.75
for the radius i used the formula C=2 x 3.14 x Radius
i used the formula of A= 3.14 x radius squared
