r = (C / π) / 2
Actually the formula of the circumference is Pi multiplied to diameter; where the diameter is equal to twice the radius.
C = π d
d = 2 r
C = π * 2r
If we need to find the radius from the Circumference then
r = (C / π) / 2
You must differentiate Pi from the number 2 because 2 is part of the radius. This is also to avoid confusion.
For example: r = 5 ; π - 3.14; find the circumference
C = π * 2r
C = 3.14 * (2*5)
C = 3.14 * 10
C = 31.40
If the circumference is given and the radius is missing, then,
r = (C/π) / 2
r = (31.4 / 3.14) / 2
r = 10 / 2
r = 5
Answer:
Each student can have 1 pencil each
Step-by-step explanation:
Since there are 4 packs of pencils with 12 pencils in each pack, you want to multiply 12 by 4 which equals 48 pencils in total. Because there are 25 students, each student can have 1 pencil. They can't have 2 pencils each though since 25 times 2 is 50 and 48 is less than 50.
