Answer:
-1/2? i dunno
Step-by-step explanation:
Circumference = 2(pi)r
Area = (pi)r^2
r = 5
5 * 2 = 10
Circumference = 10π
5 * 5 = 25
Area = 25π
Using 3.14 as pi substitute:
5 * 3.14 = 15.7
15.7 * 2 = 31.4
Circumference = 31.4
25 * 3.14 = 78.5
Area = 78.5
my answer is -24
what other i don't know
hope it will help you
