Question

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

Answer 1

A = 50.24 cm

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

`= 50.24 {cm}^(2) \\`

Explanation:

`d = 2r \\ 8 = 2r \\ (8)/(2) = (2r)/(2) \\ r = 4`

`area = \pi {r}^(2) \\ = 3.14 * 4 * 4 \\ = 50.24 {cm}^(2)`

hope this helps
