Answer:
132cm
Step-by-step explanation:
Split there firgue into shapes you know
there is a rectangle and a Trapezoid
A = bh
A = 7×4
A = 28cm
Trapezoid
A = 1/2h(b+b)
A = 1/2×8(19+7)
A = 1/2×8(26)
A = 1/2(208)
A = 104cm
Add them together
104 + 28 = 132
When the radius is doubled, the volume of a cylinder quadruple
The answer is 1.81 repeated so like 1.81818181
Since one bus holds 36 students and 4 adults, 40 people are in one bus so...
40 (6)
