romanna [79]2 years ago
6 0

Answer:

<em>Circumference:</em> 18.84 cm

<em>Area:</em> 28.26 cm^2 (exponent 2)

Step-by-step explanation:

Circumference = 2(pi)r

The diameter is 6. Means the radius is 3 (half of 6)

pi = 3.14

2(3.14) x 3 = 18.84

Circumference is 18.84 cm.

Area of a circle = (pi)r^2

(3.14)(3)^2 = 28.26 cm^2 (exponent 2)

Three fair dice are rolled, one red, one green and one blue. What is the probability that the upturned faces of the three dice a
r-ruslan [8.4K]

Answer:   \dfrac{5}{9}

Step-by-step explanation:

When we throw a die , Total outcomes =6

When we throw 3 dice , Total outcomes = 6 x 6 x 6 = 216 [by fundamental counting principle]

Given : Three fair dice are rolled, one red, one green and one blue.

Favorable outcomes : When the upturned faces of the three dice are all of different numbers i.e. no repetition of numbers allowed

By Permutations , the number of favorable outcomes = ^6P_3=\dfrac{6!}{(6-3)!}=\dfrac{6!}{3!}=6\times5\times4=120

The probability that the upturned faces of the three dice are all of different numbers = \dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}

=\dfrac{120}{216}=\dfrac{5}{9}

The probability that the upturned faces of the three dice are all of different numbers  is \dfrac{5}{9} .

If 10 feet = 2.5 inches
then 1 feet = 2.5/10 = 0.25
therefore 12 feet = 3 inches

In short the answer is 3 inches on the blueprint
