Answer:
The diameter is 14
Step-by-step explanation:
The area of a circle is given by
A = pi r^2
We know the area is 49 pi
49 pi = pi r^2
Divide each side by pi
49 pi/ pi = pi r^2/pi
49 = r^2
Take the square root of each side
sqrt(49) = sqrt(r^2)
7 =r
We want the diameter
d = 2r
d = 2*7
d = 14
Easy
plug them in
0.33=1/4(x)
times both sides by 4/1 (4/1 times 1/4=4/4=1)
0.33*4/1=4/4x
1.32=1x
1.32=x
x=1.32
2s+3<15
-3<15-3
2s<12
2 < 2
s<6

6% of $3659
= 0.06 x 3659
= $219.54

Employer contribution to his 401k
----------------------------------------
4% of $2659
= 0.04 x 3659
= $146.36
