The height of a right circular cone is multiplied by 4, but its radius remains fixed. By what factor will the volume of the cone be multiplied?
A. 1/4
B. 4
C. 8
D. 16

B

Step-by-step explanation:

Because the height is only used once (not squared) in the cone volume formula, the volume is only multiplied by 4.

step-by-step explanation:

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.
