Answer:

Step-by-step explanation:

1) The radius of circle is 4cm

The area of the circle is

[tex]\pi ^{2}[/tex]

[tex]\frac{22}{7} *4*4\\[/tex]

[tex]\frac{22}{7} *16=50.24cm^{2}[/tex]

2)

Circumference of the circle = [tex]\pi d[/tex]

Circumference of the circle = 3.14 * 10

Circumference of the circle = 31.4 inches
