Question

PLEASE HELP!!

Answer 1

Question 5)
A water ride at a local water park has a ride shaped like a cone that acts like a funnel whereby guests swirl around the cone until they drop through its center. There is one ride for adults and a similar, smaller version for children. If the adult ride has a radius of 25 feet and the child ride has a radius of 10 feet, what is the ratio between the volumes of each ride?

Answers-
A-5:2
B-15:6
C-25:4
D-125:8

Answer 2

Question 10)

Answer 3

the ratio of radii adult:child 25:10 or 5:2

then volumes is (5:2)^3 = 125:8

Answer 5

thank you!!

Answer 6

for question 10

you need to find the volume of the composite solid

the cylinder.... , radius 4 and height 35..... (47 - 12)
V = pi r^2 h

V = pi *4^2* 35

V = 560pi mm^3

Cone: V = 1/3 pi r^2 h radius = 4 height = 12

V = 1/3 pi* 4^2 *12

V = 64pi



the composite volume is V = cone + cylinder

V = 560pi + 64pi

V = 624 pi mm^3

rate of flow is 10pi mm^3

to time taken = 624pi/10pi

= 62.4 seconds


which is an answer choice...
