Answer: volume = 4275π m³
Step-by-step explanation:
The composite figure shown in the diagram is made up of a hemisphere at the top and a cone at the bottom.
Therefore,
Volume = volume of hemisphere + volume of cone.
The formula for determining the volume of a hemisphere is expressed as
Volume = 2/3πr³
Diameter of hemisphere = 30m
Radius = diameter/2 = 30/2 = 15m
Volume of hemisphere = 2/3 × π × 15³ = 2250πm³
The formula for determining the volume of a cone is expressed as
Volume = 1/3πr²h
h = height of cone = 33m
r = 15 m
Volume = 1/3 × π × 15² × 33
Volume = 2475π m³
Volume of the composite figure is
2250π + 2475π = 4275π m³
Answer:
B
Step-by-step explanation:
Answer: y = (28/4)x + 4
Step-by-step explanation:
We'll be using 20, 144 (1) and 24, 172 (2) for this
slope = y2 - y1 / x2 - x1
slope = 172 - 144 / 24 - 20
slope = 28/4
y = mx + b
y = (28/4)x + b
We can then reduce 20, 144 by 4, 28
20, 144
16, 116
12, 88
8, 60
4, 32
0, 4
The y-intercept is when x = 0, so its 4.
Plug that into y = mx + b
y = (28/4)x + 4
