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:
0.4 gallons
Step-by-step explanation:
Length of a bedroom= 20 feet
Breadth of a bedroom= 15 feet
Height of a bedroom= 8 feet
Area of walls of a bedroom= 2(l+b)×h
Area of walls of a bedroom=2(20+15)×8 
Area of walls of a bedroom= 2× 35×8 
Area of walls of a bedroom=560 
Amount of paint in 1 gallon = 400 
Number of gallons required= 
Number of gallons required= 1.4 gallons
Hence, 0.4 extra gallons required
Answer:
°
Step-by-step explanation:
The sum of all the three angles of any triangle is 180°
Putting sum of all the angles given equals to 180°

°
°

The value of the x is found on solving the given angles of the triangles.
198 x 0.05 = 9.9
198 - 9.9 = 188.1
188.1 x 0.07 = 13.167
188.1 + 13.167 = 201.267
He weighs 201.3 pounds if you round it.
