Please answer this correctly

Answer 1

Answer:

A =12.56 m^2

Step-by-step explanation:

Find the area of a circle with radius 4

A = pi r^2

A = 3.14 * 4^2

A =50.24

Since this is 1/4 of the circle, multiply by 1/4

A = 1/4 * 50.24

A =12.56 m^2

Answer 2

Answer:

12.56

Step-by-step explanation:

the formula for the area of a circle is the following:

$\pi r^{2}$

so divide that formula by 4 to get a quarter and plug in the radius for r.

$(\pi )(4^2)/4= 12.56$
