Answer:

50.27 Units²

Step-by-step explanation:

Area Of Circle:
\bold{(1)/(4) }πd²

π: 3.14

d²: 64


\bold{(1)/(4)} · 3.14 · 64

= 50.27

Answer:

A = 16pi or 50.24 units^2

Step-by-step explanation:

The area of a circle is given by

A = pi r^2

We need to find the radius

r = d/2 where d is the diameter

r = 8/2 =4

Substituting into the equation for area

A = pi (4)^2

A = 16pi

We know pi can be approximated by 3.14

A = 16(3.14)

A =50.24 units^2
