For a right circular cone, the lateral surface area is given by,

L.S.A. =\pi r\sqrt{h^{2}+r^{2}}

The value of square root of h²+r² is equal to slant height s.

So replacing the value of square root of (h²+r²) by s in the formula for lateral surface area , we have

L.S.A. = pi * r * s

where s is slant height of the given right cone.

Answer: The lateral surface area of a right cone is pi*r*s.

Option C is the correct answer.

A card is drawn randomly from a standard 52-card deck. Find the probability of the given event. (a) The card drawn is 5. The pro
Dmitrij [34]

Answer:

  • a. 1 / 13
  • b. 3 / 13
  • c. 10 / 13

Step-by-step explanation:

<h3>a.</h3>

There are four 5's in the deck. This means that, from 52 possible cards to drawn, we have 4 chances of drawing a 5. This means that the probability will be:

p = \frac{4}{52}

p = \frac{1}{13}

<h3>b.</h3>

For every suit, there are three face cards, J, Q and K. There are 4 suits, so, the total number of face cards its:

4 * 3 = 12

The total possible cards are, still, 52, so, the probability will be

p = \frac{12}{52}

p = \frac{3}{13}

<h3>c.</h3>

We know that the card drawn must be a face card, o not being a face card. There is no third choice here. So, the probability of drawing a face card OR not drawing a face car its:

p = \frac{52}{52} = 1

so

p(the \ card \  is \  a \  face  \ card) + p(the \ card \  is \  not \ a \  face  \ card) = 1

p(the \ card \  is \  not \ a \  face  \ card) = 1 - p(the \ card \  is \  a \  face  \ card)

but, we know that

p(the \ card \  is \  a \  face  \ card = \frac{3}{13}

so

p(the \ card \  is \  not \ a \  face  \ card) = 1 - \frac{3}{13}

p(the \ card \  is \  not \ a \  face  \ card) = \frac{10}{13}
