Circumference of circle = 2*pi*r
                                     = 2*22/7*42.1
                                     = 264.4 km

Therefore, the circumference of the circle is 264.4 km

Answer:

1)option b

2)option a

Step-by-step explanation:

1) circumference = 62.8 in

=> 2πr= 62.8

=> r= 62.8/(2×3.14)= 10 in

diameter = 2×10 in = 20 in

2)diameter = 14m

radius = 7 m

Area of the circle= πr² =3.14(7)²=3.14×49

= 153.86

=153.9 m²
