Answer: Total Volume = 15π + 18 π= 33π cubic mm
Step-by-step explanation:
What is the volume of the composite figure? Leave the answer in terms of π.
_33π mm3
We have a cone here conjoined to a semi-sphere.
so
Cone volume: C = (1/3)*(πr^2) * h
semi-sphere volume : V = (1/2)* (4/3) * (π * r^3)
r = 3 mm and h = 5mm
so C = (1/3)*(π (3)^2) * 5 = 15π cubic mm
V = (1/2)* (4/3) * (π * 3^3) = 18 π cubic mm
Total Volume = 15π + 18 π= 33π cubic mm

Answer:
0 and 10 for this if im wrong sorry.
Step-by-step explanation:
Triangle area formula= bh/2
Blue triangle:
10*12/2= 60
Orange triangle:
8*10/2= 40
Add the values: 40+60= 100 in^2
Final answer: 100 in^2
