Respuesta:

5.101 × 10⁸ km²

Explicación:

Primer paso: Información provista

Radio del planeta Tierra (r): 6371 km

Paso 2: Calcular el área del planeta Tierra

Si suponemos que el planeta Tierra tiene forma esférica, podemos calcular su área (A) usando la siguiente fórmula.

A = 4 × π × r²

A = 4 × π × (6371 km)² = 5.101 × 10⁸ km²

Is this one question correct
bazaltina [42]

Answer: 2/3ft or C

Step-by-step explanation: Solve for b in the area of a triangle equation, A=1/2bh. Multiply 1/2 by 2 on both sides to cancel it: A(2)=bh.  Divide both sides by h: \frac{A(2)}{h}=b

A = 2/5

h = 6/5

b = ?

Next, we can plug the numbers into this equation: \frac{2/5(2)}{6/5}=b

Multiply 2 and 2/5: 4/5 / 6/5

Take the reciprocal of 6/5: 4/5 x 5/6 = \frac{20}{30}

\frac{20}{30} ÷ \frac{10}{10} = \frac{2}{3}

A Runway is 3100 ft long and 65 ft wide what is the area of the runway in feet squared​
ivolga24 [154]

Answer:

201, 500ft²

Step-by-step explanation:

The formula for calculating area in this case is;

<em>A = w × l</em>

This means we're going to take the width of the runway (65ft) and multiply it by the length of the runway (3100ft).

(To make it easier on paper, you can swap the two numbers around, so the higher number is on top, and the smaller number is on the bottom - 3100 × 65. It won't change the answer, but it will make it quicker and easier to get to the result, and lessens the chances making a mistake.)

So the equation you need to do is;

<em>3,100 × 65 = 201, 500.</em>

Add on the units, and there's your answer;

201, 600ft²
