What is the exact volume of the cone in terms of pi?

kenny6666 [7]

Answer:

D) 3456 m

Step-by-step explanation:

Diameter of the cone = 48 m

Hence radius of the cone = $\frac{48}{2}$ = 24 m

Height of the cone = 18 m

Volume of a cone is given as $\[\frac{1}{3}*pi*radius^{2}*height\]
$

= $\[\frac{1}{3}*pi*24^{2}*18\]
$

= $\[\frac{1}{3}*pi*10368\]
$

= $\[pi*3456\]
$

Hence among the given options, option D is the correct one.

How would I put this into a solvable equation, m= ak/n?

12345 [234]

The given equation is

m = ak/n

We want to solve for k

The first step is to multiply both sides of the equation by n. We have

m * n = ak/n * n

mn = ak

The next step is to divide both sides of the equation by a. We have

mn/a = ak/a

mn/a = k

k = mn/a

The correct option is the second one

If ab = c - d, which of the following is an expression for d in terms of a, b, and c?

horsena [70]

ANSWER

$d = - ab + c$

EXPLANATION

The given expression is

$ab = c - d$

To find an expression for d in terms of a, b, and c, means we want to make d the subject of the relation.

This means that, we need to isolate d on one side of the equation while all other terms are on the other side.

We subtract from both sides of the equation to obtain,

$ab - c = - d$

We now divide through by -1, to get,

$- ab + c = d$

Or

$d = - ab + c$
