Question

pls solve it for me question no. 8 and 9

Answer 1

Answer:

Step-by-step explanation:

PIPE:

d=20cm

r = 10cm = 10/100m =1/10m

h=?

Tank

D=10m

R=5m

H=2m

Volume of water trvelled through the pipe = volume of tank (cylinder)

$\pi r^{2} h = \pi R^{2} H$

1/10 × 1/10 ×h = 5×5×2

1/10 × 1/10 × h = 50

h = 50× 10 ×10

h = 5000m

h =5km
