Answer:

42.2 cubic inch

Step-by-step explanation:

Applying,

V = πr²h/3.................... Equation 1

Where, r = radius of the circular base, h = height of the cone, π = pie.

But,

r = P/2π..................... Equation 2

Where P = circumference of the circular base.

Substitute equation 2 into equation 1

V = π(P/2π)²(h)/3

V = P²h/12π.................. Equation 3

From the question,

Given: h = 18.4 in, P = 9.3 in

Constant: π = 3.14

Substitute these values into equation 3

V = (9.3²)(18.4)/(12×3.14)

V = 42.2 cubic inch

A card is drawn from a pack of 52 cards. Find the probability of drawing an ace given that it is diamond.4/521/132/134/13
ICE Princess25 [194]

Solution:

The probability of an event is expressed as

P(event)=\frac{number\text{ of desired outcome}}{number\text{ of possible outcome}}

In a pack of 52 cards, we have

\begin{gathered} number\text{ of diamonds=13} \\ number\text{ of ace= 1} \end{gathered}

Thus, we have the probability to be evaluated as

P(ace)=\frac{1}{13}

Kevin sold 2 unicycles and 1 bicycle for a total of $110. Greg sold 4 unicycles and 3 bicycles for a total cost of $268. What is
RSB [31]
Simultaneous Equations

2u +   b = $110
4u + 3b = $268

(x2) 4u + 2b = $220
(x1) 4u + 3b = $268

<em />If both the matching coefficients are the same, we subtract equation 2 from equation 1

2b - 3b = -b
$220 - $268 = $-48
-b = -$48
b = $48

If you want to find out what a unicycle costs...
Substitute b = $48 into the first equation
2u + $48 = $110
Balance the equation, whatever happens on one side, happens on the other.
2u + $48 (-$48) = $110 (-$48)
2u = $62
2u(/2) = $62(/2)
u = $31
