Step-by-step explanation:
as any other fully symmetric 3D object, the volume is
base area × height.
the area of a circle is
pi×r²
so, we have in our case
pi×13²×9 = 3.14×169×9 = 4,775.94 cm³
Answer:
Step-by-step explanation:
The formula for the volume of a cone is
V = (1/3)r²h, where r is the radius and h is the height.
Unfortunately, you seem to have given the diameter twice.
Which is the diameter of the base, 6 inches or 4 inches? What is the height of the cone, in inches?
Answer:
Step-by-step explanation:
B, D, E
because you have a quotient when you divide and has the same rules as multiplication
The area of a rectangle is calculated through the equation, V = L x W. That of the circle is equal to V = πr². These areas should be equal,
V = L x W = πr²
Substituting the known values,
2 ft x 11 ft = (22/7)(r²)
The value of r is sqrt 7.
Ok this is not as hard as it seems
(4.5 feet)^2 times the number of students (13)
20.25 x 13
263.25 is the correct answer
I hope it helps :<
