Hello!

\mathcal{GIVEN:}

  • Diameter of the circle = 12 cm

\mathcal{TO\:FIND:}

Area of the Circle

\mathcal{SOLUTION:}

A=πr²

Hey! We have the diameter, not the radius.

Don't panic. In order to find the radius, we should divide the diameter by 2.

So, the radius is 6.

Plug it into the formula:

A=π(6)²

A=π(36)

A≈113 cm

Hope it helps!

Good luck and enjoy your day!

Suppose that a visitor to Disneyland has a 0.74 probability of riding the Jungle Cruise, 0.62 probability of riding the Monorail
erastova [34]

Answer: 0.98

Step-by-step explanation:

Let J denotes Jungle Cruise , M denotes Monorail and H denotes Matterhorn.

As per given ,

P(J) = 0.74,  P(M) =  0.62, P(H) = 0.70

P(J∩M) = 0.52,  P(J∩H)= 0.46 , P(M∩H)=0.44

P(J∩M∩H)=0.34

Now , the required probability:

P(J∪M∪H) = P(J) + P(M)  + P(H) - P(J∩M) - P(J∩H) - P(M∩H)+ P(J∩M∩H)

= 0.74+0.62+0.70-0.52-0.46-0.44+0.34

= 0.98

Hence, the probability that a person visiting Disneyland will go on at least one of these three rides= 0.98 .

Xin graphs the equation y =4x - 6.
Art [367]

Answer:

Both D and E are true statements.

Step-by-step explanation:

When you have the base form of slope-intercept form:

y = mx + b

The m (which is the coefficient of x) is the slope of the line. In this case that would be 4.

The b is the intercept. In this case it would be -6

GarryVolchara [31]

Answer:

Step-by-step explanation:

Take an easier number.  Suppose you owe your mother = 10 dollars and your father 15. Which one is the bigger debt? Isn't it your father.? So how do you represent the two debts.

Father = - 15

Mother = - 10

Which number is bigger? - 10. Remember the question is bigger. You would rather own just 10 dollars.

So which number is "larger"?

Isn't it -4488. If it was money and you owed it, would it be the debt you would rather have than -4820
