Perimeter of bigger disc = 2π*24 inch
perimeter of bigger disc = 2π*8 inch
number of rotations =2π*24/2π*8 = 3
Answer:
Both Triangle are congruent because they have equal sides (the same amount of ticks on each side) The triangles are congruent.
Step-by-step explanation:
For any value, e.g. a, to the nearest x units, the upper and lower bounds are:
(a + x/2) and (a - x/2)
For your question, there are three dimensions so:
Dealing with the first one, we have 24 cm to the nearest 2 cm so the boundaries are:
Upper boundary: 24 + 2/2 = 25
Lower boundary: 24 - 2/2 = 23
The second dimension is the same as the first in value and is also given to the nearest 2 cm so the boundaries are the same as for the first.
The third dimension is 20 cm to the nearest 2 cm so the boundaries are:
Upper boundary: 20 + 2/2 = 21
Lower boundary: 20 - 2/2 = 19
To get the largest possible area, we take the upper bounds of all the dimensions and multiply them so:
25 * 25 * 21 = 13125 cm³
Answer:
-4
Step-by-step explanation:
in 6x3-4x4+22 4 is the biggest exponent
the coefficient of the biggest exponent is -4 becuase it would be -4(4)
therefore the leading coefficient is -4
