50.2

Step-by-step explanation:

The equation to find the area of a circle is $a=\pi r^{2}$ .

First, substitute your numbers in place of the variable:

$A=\pi 4^{2}$

Next, square the radius:

$A=\pi 16$

Then, multiply it out to get:

A=50.24

Then, pick the closest answer which is 50.2

-12n=77+19
-12n=96
n=-8

2. 16+3f=14
3f=14-16
3f=-2
f=-2/3

3. 15t+4=59
