L=2C+11(D+d)/7+(D-d)^2/4C


what is L(in inches)if D=12 inches d=2inches and C=25 inches

Just substitute values and calculate.

L = 50+11(14)/7+10^2/4(25)

L=50+154/7+100/100

L=50+22+1
L=73

To find the value of L, you need to substitute the given values of D, d, and C into the equation:

L = 2C + 11(D + d)/7 + (D - d)^2/4C

Given:
D = 12 inches
d = 2 inches
C = 25 inches

Now, let's substitute the values into the equation:

L = 2(25) + 11(12 + 2)/7 + (12 - 2)^2/(4*25)

First, calculate the values inside the parentheses:

L = 50 + 11(14)/7 + 10^2/(4*25)

Next, perform the operations:

L = 50 + 154/7 + 100/100

Convert the fractions to decimals:

L = 50 + 22 + 1

Finally, add the values:

L = 73

Therefore, L is 73 inches.
