Answer 1

Answer:

Step-by-step explanation:

5. a.

sides are 50cm ,60 cm , 20 cm

volume= 50 x60x20 = 60000 cc =60 litre                    1cc= 0.001 litre

b.

0.2 litre can be filled in 1 sec

1     litre can be filled in 1/0.2

60  litre can be filled in 1/0.2x60 = 300 sec = 5 minute

6.

volume of AEBC = 140cm x 40cm x 30cm =168000 cc

area of ECD = (20^2 x3.1416) /2=628.31 cm             ( area of circle=π radius^2

                                                                                      as it is a semi circle                                  

                                                                                           π radius^2 /2)

volume of ECD =628.31cm x 140cm= 87963.4 cc

total volume = ECD +AEBC =255963.4 cc

u should give some respect after this
