Question

Find the area of a circle using 3.14 as pie d=8cm

Answer 1

Answer:

A = 50.24 cm

Step-by-step explanation:

Area formula of a circle:

A = π r²

diameter- r+r

which means that your diameter(8) divided by 2 = 4

r of circle= 4

A= 3.14(4²)

A = 3.14(16)

A = 50.24 cm

Answer 2

Answer:

$= 50.24 {cm}^{2}$

Step-by-step explanation:

$d = 2r \\ 8 = 2r \\ \frac{8}{2} = \frac{2r}{2} \\ r = 4$

$area = \pi {r}^{2} \\ = 3.14 \times 4 \times 4 \\ = 50.24 {cm}^{2}$

hope this helps
