The volume of cone is 24 or 75.398 cubic centimeters, if the cone has a radius of 3 centimeters and height of 8 centimeters.
Step-by-step explanation:
The given is,
Formula for volume of cone,
Where, B =
Volume,
From the given,
Radius, r = 3 centimeters
Height, h = 8 centimeters
volume,
Volume of cone, V= 24 (volume in terms of
)
( or )
Volume, V = (24 × 3.14 ) ( ∵ =3.14 )
V = 75.398 cubic inches
Result:
The volume of cone is 24 or 75.398 cubic centimeters, if the cone has a radius of 3 centimeters and height of 8 centimeters.
Answer:
see explanation
Step-by-step explanation:
Given
f(x) = - 2x² + 4x - 2
To find the y- intercept set x = 0
f(0) = 0 + 0 - 2 = - 2 ← y- intercept
The equation of the axis of symmetry is of the form x = c
where c is the value of the x- coordinate the line goes through.
Given the equation in standard form
with a = - 2, b = 4 then the axis of symmetry is
x = - = -
= 1
Equation of axis of symmetry is x = 1
