Formula: Area = pi x radius(squared)

The radius 5.5mm is half of the diameter 11mm

Answer: 3.14159 x 5.5mm^2 = 95.033mm^2

The diameter is twice the radius,

$d=2r$

$A = \pi r^2 = \pi (d/2)^2 = \pi d^2/4$

$d=11$

$A = \pi d^2/4 = \pi (11^2/4) = \dfrac{121}{4} \pi$

Answer: $\dfrac{121}{4} \pi$

Use the zero product property to find the solutions to the equation x^2+x-30=12

lukranit [14]

Answer:

Due to there being no negatives in this equation, you can pretty much just eliminate the first 3 answers.

However in working out, here is what I did.

x^2 + x - 30 = 12 (+30)

= x^2 + x = 42

Then you can conclude that the answer is D, due to 6 x 6 = 36, plus 7 equaling 42.

A card is picked from a standard deck of 52 cards. Determine the odds against and the odds in favor of selecting a red face card

timama [110]

<h3>The probability of picking a red face card from the deck is $(\frac{3}{26} )$ </h3><h3>The probability of NOT picking a red face card from the deck is $(\frac{23}{26} )$ </h3>

Step-by-step explanation:

The total number of cards in the deck = 52

The total number of red( Diamond + Hearts) face cards in the given deck

= 2 Red Queens + 2 Red jacks + 2 Red kings = 6 cards

Let E : Event of picking a red face card from the deck

Now , P( any event) = $\frac{\textrm{The number of favorable observations}}{\textrm{Total number of observations}}$

So, here P(Picking a red face card) = $\frac{\textrm{The number of red face cards}}{\textrm{Total number of cards}} = (\frac{6}{52} ) = (\frac{3}{26})$
