Answer:

Below in Bold! ^^

Step-by-step explanation:

Let's work out the circumference first.

C=πd C=circumference π=pi d=diameter

Stick in the value of d

C=π·8

Multiply

C≈25.1 m

Now let's find the area.

A=πr^2 A=area r=radius (r^2=r·r)

Radius=d:2

r=8:2

r=4

Stick in the values

A=π·4^2

A=π·16

Multiply

A≈50.3 m^2
