The Port of Tauranga Company has allowed Gull to build a new cylindrical petrol storage tank at Mount Maunganui.
To help plan for this tank, complete the following calculations (show all working)
1a-(L3) The tank will site on a rectangular site 60 m long by 30 m wide. This needs to be laid with cobblestones. Work out the area in m2
1b-(L4) Work out the area in hectares.
1c-(L3) Wooden boxing will need to be placed around the outside of this rectangle. What is the total length of wood needed?
2a-(L3) The tank has a diameter of 20 m. What is the radius?
2b-(L4) What area will the base of the tank cover?
3a-(L5) The concrete foundations need to be 15 cm thick. What volume of concrete will be needed for the base? (assume the foundations will be circular)
3b-(L5) The capacity of a concrete truck is 6 cubic metres. How many trucks will be required to pour the base?
3c - (L6) Steel reinforcing needs to be used for the foundation. A total length of 1000 m will be used. The steel reinforcing is a solid cylindrical rod, 1.5 cm in diameter. What will be the new volume of concrete required taken into account the volume of the steel reinforcing?
3d - (L6) Cost for concrete delivery is $130 per truck plus $40 per cubic metre of concrete. What will the total cost of the concrete be?
4a - (L5) Once completed, the tank will hold 16, 000, 000 litres. How many cubic metres does this equal?
4b - (L6) How tall must the tank be?
4c - (L6) If two thirds full with fuel, how long will it take to pump in the remaining third if a tanker can pump 23 cubic metres of fuel per hour?
