Answer:

≈ 201

Step-by-step explanation:

V= πr²h/3

V= 3.14*4²*12/3= 200.96 ≈ 201

Answer:

200.96 units

Step-by-step explanation:

Use the formula for the volume of a cone $V=\pi r^{2} \frac{h}{3}$

Plug in the values ( $\pi$ =3.14) and multiply them all out

Not sure how to solve this one

Alex73 [517]

Answer:

$x\approx 63.4^0$

Step-by-step explanation:

In the given right triangle,

Measure of angle = x°

Opposite side of the angle = 12 units

Adjacent side of the angle = 6 units

By taking tangent ratio of the given angle,

tan(x°) = $\frac{\text{Opposite side}}{\text{Adjacent side}}$

= $\frac{12}{6}$

= 2

$x^0=\text{tan}^{-1}(2)}$

$x=63.43^0$

$x\approx 63.4^0$

find real numbers a, b, and c so that the graph of the function y=ax^2+c contains the points (-1,6), (2,7), and (0,1)

Paraphin [41]

This gives you three simultaneous equations:

6 = a + c
7 = 4a + c
1 = c

c = 1

If c =1,

6 = a + 1
a = 5

This doesn't work in the second equation, so the quadratic that goes through these points is not in the form y = ax^2 + bx + c
Was there supposed to be a b in the equation?
