The volume of a cone is
V = (1/3) π r² h
where r =  radius of the base
h =  the height.

The volume of the frustum is
(1/3)π(7.5²)(11+8) - (1/3)π(3.5²)(8)
=(1/3)π(7.5²)(19) - (1/3)π(3.5²)(8)

The 3rd choice is the correct answer.

Answer:
\frac{1}{ 3}  \pi (7.5^{2})(19) -  \frac{1}{3}  \pi (3.5^{2})(8)

Answer:

X=5

Step-by-step explanation:

f(1)= -1^2+4(1)+12=15

f(2)= -2^2+4(2)+12=16

f(3)= -3^2+4(3)+12=15

f(4)= -4^2+4(4)+12=12

f(5)= -5^2+4(5)+12=7

g(1)=1+2=3

g(2)=2+2=4

g(3)=3+2=5

g(4)=4+2=6

g(5)=5+2=7

so g(5)=f(5)= X=5

Arthur wants to buy an item that costs p dollars before tax. Using the Florida tax rate of 6%, write two different expressions t
REY [17]

The different expressions that represent the price of the item after tax will be p + 6/100p and p + 0.06p.

<h3>How to illustrate the expression?</h3>

The first expression will be:

= p + (6/100 × p)

= p + 6/100p

The second expression will be:

= p + (6% × p)

= p + 0.06p

It should be noted that both expressions are equal.
