Answer:

a. 1.32 m³

b. 1.32 kL

c. 105.04 m

Step-by-step explanation:

Area of roof = 110 m²

Rain fall = 12mm = (12/1000)m = 0.012 m

(a) Volume of water that fell on roof = Area of roof × Rain depth

    = 110 × 0.012

    = 1.32 m³

(b) 1 m³ = 1 kL

 ∴ 1.32 m³ = 1.32 kL

(c) Radius of tank = (4/2) = 2 m

    Volume of tank = Base area × Height

     = πr²h

     = π × (2)² × h

     = 4πh

     The volume added to the tank must be equal to the volume which falls on roof.

     i.e. Volume of tank = Volume of water that fell on roof

      or, 4πh = 1.32

      or, h = 1.32 / (4π)

      ∴   h = 0.10504 m = (0.10504/100)cm = 10.504 cm

∴ The water level rises by about 10.504 cm.

Hi there!

So If Ron worked 2 hours he collected a total of 248 newspapers.
Sharon worked one hour collecting 132 newspapers.
Kent worked 3 hours collecting 354 newspapers.
248+132+354=734

Therefore Kent worked 3 hours and Sharon worked 1 hour.

Hope this helps!
