Give the exact answer in simplest form.
square kilometers

Answer 1

Explanation:

Area of a circle = πr²

Radius (r) =1/2 Diameter

=60/2

=30km

Area = π x (30)²

= π x 900

= 2027km²

Answer 2

28.27 rounded orrrr 28.27433388 not rounded.

Explanation:

area of circle=πr^2

radius=3 km

3^2=9

9*π
