Answer:
Question 9: A. 27/2
Question 10: A. 9/2
Step-by-step explanation:
I believe Silem2020 is correct, I Checked on paper.
Q#9: A 27/2
Q#10: A 9/2
<u>Q#9:</u>
these triangles are similar so we have to take the ratios:
8/(12+8)=8/20
8/20=9/(9+x)
8*(9+x)=20*9
72 +8x=180
108=8x
x=27/2
<u>Q#10:</u>
6/10=x/(12-x)
6(12-x)=10x
72-6x=10x
72=16x
x=9/2

cylinder:
V = πr²h
V = 3.14(2)² * 3
V = 3.14(4) * 3
V = 3.14(12)
V = 37.7m³
rectangular prism:
V = lwh
V = (2.4)(9)(5)
V = 108m³
the entirety of the sculpture:
V = volume of cylinder + volume of rectangular prism
V = 37.7 + 108
<u>V = 145.7m³</u>
