Can someone answer this question for me??
Determine ratio of A to B. Round as indicated.

A = 36 π square inches is the area of a circle with diameter 12 inches . B = 144 square inches is the area of a square with sides of length < 12 inches .
a.) 4/π b.) 6/π c.) π/4 d.) π/6

  c.)  π/4

Step-by-step explanation:

Form the desired ratio and simplify:

  A / B = circle area / square area

  = (36π)/(144) = (π·36)/(4·36) = π/4 . . . . matches choice C

step-by-step explanation:

step by step resolutions

1) n+n+1+n+2=51

3n+3=51

3n=48

n=16

the three numbers are 16, 17 and 18.

2) x+15=4x

3x=15

x=5

3) the two digits are x and y.

y=3x

(10x+y)+(10y+x)=88

y=3x

11x+11y=88

y=3x

x+y=8

x+3x=8

x=2

the original number can be either 28 or 82.

4) n+(n+2)+(n+4)=48

3n+6=48

3n=42

n=14

the numbers are 14, 16 and 18.

5) y=x+3

10y+x+10x+y=143

y=x+3

11x+11y=143

y=x+3

x+y=13

x+x+3=13

2x=10

x=5

the original number can be 57 or 75.

hope this !
