Encuentre el radio y el área de círculos cuya circunferencias tienen las siguientes medidas

Mathematics
1 answer:
Vadim26 [7]3 years ago
6 0

Answer:

Los radios de los círculos son r_{1} \approx 9.995, r_{2} \approx 2.013, r_{3} \approx 7.592, respectivamente.

Las áreas de los círculos son A_{1} \approx 313.845, A_{2} \approx 12.730, A_{3} \approx 181.077, respectivamente.

Step-by-step explanation:

La circunferencia (s) se calcula mediante la siguiente fórmula:

s = 2\pi\cdot r (1)

Donde r es el radio del círculo.

Una vez hallado el radio, se determina el área de la figura geométrica (A) mediante la siguiente fórmula:

A = \pi\cdot r^{2} (2)

Si conocemos que las circunferencias son s_{1} = 62.8, s_{2} = 12.65 y s_{3} = 47.7, respectivamente:

1) Radios de los círculos

r_{1} = \frac{s_{1}}{2\pi}, r_{2} = \frac{s_{2}}{2\pi}, r_{3} = \frac{s_{3}}{2\pi}

r_{1} \approx 9.995, r_{2} \approx 2.013, r_{3} \approx 7.592

2) Áreas de los círculos

A_{1} = \pi\cdot r_{1}^{2}, A_{2} = \pi\cdot r_{2}^{2}, A_{3} = \pi\cdot r_{3}^{2}

A_{1} \approx 313.845, A_{2} \approx 12.730, A_{3} \approx 181.077

The probability that a 4 shows up is 0.20 and the proportion of 3's rolled is 0.467

<h3>The probability that a 4 shows up</h3>

From the list of numbers, we have:

  • Sides = 5 i.e. numbers 1 to 5
  • n(4) = 1 i.e. sides labelled 4

The probability that a 4 shows up is then calculated as:

P = n(4)/Sides

This gives

P = 1/5

Evaluate

P = 0.2

<h3>The proportion of 3's rolled</h3>

In the list of numbers, we have:

  • Total = 15
  • Number of 3's = 7

The proportion of 3's rolled is then calculated as:

P = Number of 3's/Total

This gives

P = 7/15

Evaluate

P = 0.467

Hence, the proportion of 3's rolled is 0.467

Answer:

B

Step-by-step explanation:

Using the rule of exponents

a^{-m} = \frac{1}{a^{m} }

Given

y = 12 × 3^{x} ← substitute x = - 2 into the expression

y = 12 × 3^{-2} = 12 × \frac{1}{3^{2} } = 12 × \frac{1}{9} = \frac{12}{9} = \frac{4}{3} → B

Simplify : 4x + 8y - 3x + 2y

We need to combine like terms, so 4x-3x, and 8y+2y. x+10y is it simplified
