The radius of a circle is 12 in. Find its circumference in terms of
π
π.

It would be 24(π)

Step-by-step explanation:

This is due to the circumfenrece equation for a circle being (π)D, with D as the diameter which is 2x the radius, so 12x2=24.

After this, it is 24(π), though leave it at there since it is meant to be written in terms of it. You're now done!

75.4 in. ???

Step-by-step explanation:

Come back if its not correct.

75 tickets have been sold so far.

step-by-step explanation:

in this question it is clearly mentioned that 45 children's tickets have been sold and this number is 60% of the total tickets sold.

now let's assume the total number of tickets sold be x.

then 60% of x = 45

⇒

⇒ x(.6) = 45

by dividing with .6 on both the sides of the equation

⇒ x = 75

therefore 75 tickets have been sold so far.
