Answer:
clay sphere gives more clay for less money
Step-by-step explanation:
Volume of cone=1/3πr^2h
=1/3*3.14*(9^2)*12
=1/3*3.14*81*12
=3,052.08/3
=1017.36 inches^3
Volume of a cyclinder=πr^2h
=3.14*(9^2)*12
=3.14*81*12
=3,052.08 inches^3
Volume of a sphere=4/3πr^3
=4/3*3.14*(9^3)
=4/3*3.14*(9^3)
=4/3*3.14*729
=9,156.24 / 3
=3,052.08 inches^3
Clay cone=$12
Clay cyclinder=$30
Clay sphere=$28
Which is the best to buy
Comparing volume
Volume of sphere=3,052.08 inches^3
Volume of cyclinder=3,052.08 inches^3
Volume of cone=1017.36 inches^3
Sphere and cyclinder both have the same volume which is 3 times more than volume of a cone
Clay sphere cost $28 which is cheaper than clay cyclinder at the same volume.
Therefore, clay sphere gives more clay for less money
Answer:
A, B, C, & E
Step-by-step explanation:
A) 19,456 ÷ 6 = 3,242
(2/3 is 0.666666666 etc)
B) 28,765 ÷ 13 = 2,212.692308...
C) 4,145 ÷ 3 = 1,381
(2/3 is 0.666666666 etc)
D) 4,165 ÷ 17 = 245
(Not bolded because it is not an answer)
E) 44,312 ÷ 16 = 2,769.5
C -> When dividing by three, if the first number's values do not add up to a multiple of 3 there will be a remainder. Example from your problem,
4,145 -> 4 + 1 + 4 + 5 = 14 -> 14 is not a multiple of 3, so there is a reminder
D -> No decimal / fraction, no remainder!
Have a nice day!
