Question

can someone help me with this? Thank you!

Answer 1

Answer:

12.56 m²

Step-by-step explanation:

Given,

π = 3.14

d = 4m

To find : A

Formulas : -

1 ) r = d/2

2 ) A = πr²

r = 4 / 2 = 2m

A = πr²

  = 3.14 x 2²

  = 3.14 x 2 x 2

A = 12.56 m²

Answer 2

$\qquad\qquad\huge\underline{{\sf Answer}}$

Here we go ~

$\qquad \sf  \dashrightarrow \: a = \pi {r}^{2}$

• r = d/2 = 4/2 = 2 m

$\qquad \sf  \dashrightarrow \: a = 3.14 \times {2}^{2}$

$\qquad \sf  \dashrightarrow \: a = 3.14 \times {4}^{}$

$\qquad \sf  \dashrightarrow \: a = 12.56 \: \: m {}^{2}$
