A= πr^2
r=9
A= π(9)^2
A= 9x9=81
A=81π

In case that you have to use π
Multiply π(3.14)
3.14 times 81=254.34

What is the exact volume of the cone with a radius of 7in and a height of 4in use 3.14 for π
vfiekz [6]

Answer:

The exact volume of the cone is \frac{196}{3}\pi\ in^{3}

Step-by-step explanation:

we know that

The volume of the cone is equal to

V=\frac{1}{3}\pi r^{2}h

we have

r=7\ in

h=4\ in

substitute the values

V=\frac{1}{3}\pi (7^{2})(4)=\frac{196}{3}\pi\ in^{3}

Analyze the graph h(x).
Dominik [7]

Answer:

D h(x) = f(x)×g(x)

Step-by-step explanation:

h(x) has a wave with 2 changes in direction.

so, this needs to be an expression of the third degree (there must be a term with x³ as the highest power of x).

and that is only possible when multiplying both basic functions. all the other options would keep it at second degree (x²) or render it even to a first degree (linear).
