1.) The first person who requires your assistance is Tina the bearded lady. Tina’s side job is to look after the elephants (she double majored at circus university.)

a. Tina must fill the semi-circular trough shown above with peanuts. Tina knows that the store bought peanuts she can buy will each fill up 1.5 ft3. How many bags of peanuts should she buy to fill up the 12 troughs? [3 marks]

b. Tina notices that the trapezoid shaped water trough has sprung a leak. If the leak drains at a rate of 1.37ft3/s how long until the trough empties (the hole is in the bottom of the trough?) [3 marks]
