Use the equation A=(1/2)bh
Replace b with 7
Replace h with 12
A=(1/2)(7)(12)
A=(1/2)(84)
A=42
The mass of lead cylinder is: 859.10 grams
Step-by-step explanation:
In order to find the mass of a cylinder we have to find the volume first
Given
Radius = r = 2 cm
Height = h = 6 cm
The volume of cylinder is given by:

Putting the values

Now,
Density of lead per cm^3 = 11.4g

The mass of lead cylinder is: 859.10 grams

Since ZY bisects GE and XY bisects EF, and both ZY and XY both bisect GF, then XY ~ ZE and ZY ~ XE.
Therefore ZE = XY = 5
And GE = 2× ZE (because bisected segments are = and therefore ×2 = long segment).
So GE = 2ZE = 2×5 = 10
An object in geometry with no width, length or height is a point
Answer:
Slope is -2
Step-by-step explanation:
( -3, 7) and ( -2, 5)
Slope:
m=(y2-y1)/(x2-x1)
m=(5-7)/(-2+3)
m = (-2)/1
m = -2
