Answer:
59)
Therefore the height of the pyramid is 14 meter.
60)
Therefore the Diameter of Cone is 17.32 cm.
Step-by-step explanation:
59 )
Given:
Shape is Rectangular Pyramid,
Length = 3 meter
Width = 8 meter
Volume of Rectangular Pyramid = 112 cubic meter
To Find:
Height:
Solution:
We Know,
Substituting the given values we have
Therefore the height of the pyramid is 14 meter.
60 )
Thee shape is of Cone
Given:
Height= 5 cm
Volume of cone = 125 π cm³
To Find:
Diameter of a cone = d = ?
Solution:
We know,
Substituting the given values we have
Therefore the Diameter of Cone is 17.32 cm.
The reactangle has an area of x.
So that means two numbers multiplied to each other equal to x. We can just think of itwo numbers that when multiplied equal to x as a and b.
So that means the side lengths are <u />a and b. And ab = x (will be using this right next).
And it was multiplied by some scale factor that made the new area 9x. So if the scale factor is y, then:
y can not equal to -3, because the length of a side of any polygon can never be negative.
So the dilation is 3.
And so if the dimension is 5 by 8.
Then the area is
And so then
And then after the dilation, it would be
We could check it another way too. Since we said the scale factor is 3, then:
So basically 15 by 24 is the new dimensions :)
