The slope is 1. The picture will show you why.
Turn the feet into meters 1 meter = 100cm and if there is 12cms in a foot than divide 100cm by 12cm and you get 8.3ft
Answer:
it will be equal to
okay....
Step-by-step explanation:
volume of a cuboid = l × b × h
( where l = length, b = width , h = height )
so volume of given cuboid = ( 3x × 2x × 2x )
hence volume =
Answer:
7 = 49 ÷ r
Step-by-step explanation:
To find the equation that is true when r = 7, we need to find a number after the equals sign that is a multiple of 7.
Multiples of 7:
7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 77...
Therefore, the only answer option in which the number after the equals sign is a multiple of 7 is:
7 = 49 ÷ r
To prove this, input r = 7 into each of the equations:
6 = 30 ÷ r
⇒ 6 = 30 ÷ 7
⇒ 6 ≠ 4.285... ← incorrect!
7 = 54 ÷ r
⇒ 7 = 54 ÷ 7
⇒ 7 ≠ 7.714... ← incorrect!
7 = 49 ÷ r
⇒ 7 = 49 ÷ 7
⇒ 7 = 7 ← correct!
9 = 72 ÷ r
⇒ 9 = 72 ÷ 7
⇒ 9 ≠ 10.285... ← incorrect!
Step-by-step explanation:
volume of the cyclinder=πr²h
=π×6²×12
=432π cm³
volume of a cone=1/3πr²h
=1/3π×9×8
=24π cm³
number of cones=432π/24π=18 cones
