A 12.6 m²
B 25.1 m²
C 50.2 m²
D 158.0 m²

Answer 1

Answer:

C: $50.2 \, \textsf{m}^2$

Step-by-step explanation:

To find the area of a circle, we can use the formula:

$\Large\boxed{\boxed{\textsf{Area} = \pi \times \textsf{radius}^2 }}$

Given:

Radius = 4 m

Now,

Substitute this value in above formula:

$\textsf{Area} = 3.14 \times 4^2$

$\textsf{Area} = 3.14 \times 16$

$\textsf{Area} = 50.24 \, \textsf{m}^2$

$\textsf{Area} = 50.2 \, \textsf{m}^2\textsf{(in nearest tenth)}$

So, the best approximation for the area of the circle is:

C: $50.2 \, \textsf{m}^2$

Answer 2

Answer:

C)50.2 m²

Step-by-step explanation:

The area of a circle is given by the following formula

$A_{\rm Circle}= \pi r^2$

plug in the value of r and simplify

$A_{\rm Circle}= \pi r^2= 3.14*4^2=\boxed{50.24m^2}$
