What is the circumference of a circle with a diameter of 7 inches? (use for pi) asap

C = 7pi = 21.98 inches

Step-by-step explanation:

The circumference of a circle is given by

C = pi * d

 where d is the diameter

C = pi * 7

If we use 3.14 as an approximation for pi

C = 3.14 * 7

C =21.98 in

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.
