Question

Hey, I'm not sure if I'm wrong or not but wouldn't the answer be c divided by pi? or c/pi

Answer 1

You are correct

It is C divided by PI

Explanation:

c=pi x D

Using substitution method replace letters with numbers

12(c)=3(pi) x 4(d)

we want 4(d) the subject of the formula

4(d)=

12/3 =4

so it is 4(d)=12(c)/3(pi)

so D=C/PI
