Answer:
D. 151 cu. in.
Step-by-step explanation:
Given: Cone; Radius = 4 in, Height = 9 in.
To find: The volume of the specified cone
Formula:
Solution: A cone is a solid that has a circular base and a single vertex. To calculate its volume multiply the base area (area of a circle: π × r²) by height and by : volume = ( ) × π × r² × h.
Answer:
Infinitely many solutions
Step-by-step explanation:
Infinitely many solutions
The formula for density is d = m/v.
d = density
m = mass
v = volume
The volume of the rock is 15 cubic centimeters.
The mass of the rock is 45 grams.
Now just plug these into the formula and solve.
d = 45/15.
45/15 = 3.
The density of the rock is 3 grams per cubic centimeters.
