lord [1]

Given:

Area of a circle, A=50.265 sq. units.

Radius of circle, r = 4 units.

To find:

The value of π to the nearest thousandth.

Solution:

Formula for area of a circle is

A=\pi r^2

\dfrac{A}{r^2}=\pi

Ar^{-2}=\pi

Now, using Ar^{-2} expression, we can find the value of π.

\pi=50.265904(4)^{-2}

\pi=\dfrac{50.265904}{4^2}

\pi=\dfrac{50.265904}{16}

\pi=3.141619

Approximate the value to the nearest thousandth (three digits after decimal).

\pi\approx 3.142

Therefore, the approximated value of π is 3.142.

Una botella de agua de medio decimetro cubico se llena en 35 segundos .Con el mismo flujo de agua,¿En cuantos minutos se llenari
Amanda [17]

Answer:

5,250 minutes

Step-by-step explanation:

0.5 cubic Centimeter = 0.0005 liter

So, 4.5 liters = 4,500 cubic Centimeter

Time required for 0.5 cubic Centimeter = 35 seconds

So, we can calculate the total time required by using following formula

Total time required = (Time required for 0.5 cubic Centimeter × 2 ) × 4,500 cubic Centimeter

So, Total time required = (35 seconds ×2 ) × 4,500

= 70 × 4,500

= 315,000 seconds

= 5,250 minutes
