Answer:
Step-by-step explanation:
You need to find the distance between the 3 lengths of the lines from the given points
ef = sqrt ( 6-4) ^2 + 2-2^2) = sqrt 4 = 2
fg = sqrt (6 - 2)^2 + 4-4^2 = sqrt16 = 4
ge = sqrt (6-4)^2 + (2-6)^2) = sqrt 20 = 4.47
circumference = 2 + 4 + 4.47 = 10.47
Answer:
7.2
Step-by-step explanation:
So it says they all have the same area
6 * 6 = 36
4 * 9 = 36
So now you can divide to find the answer of Figure 2
36 divided by 5 is 7.2
You can check you your answer by multiplying
5 * 7.2 = 36
Answer:
891 cm³
Step-by-step explanation:
The volume (V) of the prism is calculated as
V = Ah ( A is the area of cross- section and h is the height (
The cross- section is a trapezium with area (A) calculated as
A =
h ( a + b)
where h is the perpendicular height and a, b the parallel bases
Here h = 9, a = AB = 14 and b = CD = 8 , thus
A =
× 9 × (14 + 8) = 4.5 × 22 = 99 cm² , thus
V = 99 × 9 = 891 cm³
