Question

The circumference of a circular island is 34.54 miles. What is the area of the
island?

Answer 1

Answer:

A = 94.99

Step-by-step explanation:

C = 2(3.14)r

34.54 = 2(3.14)r

34.54 = 6.28r

r = 34.54/6.28

r = 5.5

A = (3.14)r²

A = (3.14)5.5²

A = (3.14)30.25

A = 94.985

Answer 2

Answer:

95miles²

Step-by-step explanation:

The circumference of a circular island = 34.54 miles.

2πr=34.54miles

πr=17.27mile

r=17.27/πmile

the area of the island=πr²=π×{17.27/π}²=95miles² approx
