Find the area of a circle with a radius of 11ft. Use 3.14 or 22/7 for pie.

alexgriva [62]

Solution:

Note that:

Area of circle: πr²
r = 11 ft.

Substitute the radius in the expression to find the area of the circle.

(π)(r²)
=> (22/7)(11²)
=> (22/7)(121)
=> 380.29 ft² (Rounded)

suppose that two people standing 3 miles apart both see the burst from a firework display.after a period of time ,the first pers

The fireworks display occur at 550.331 ft

The generic equation for a hyperbola provided by: is the best method for solving the problem in this instance.

$\frac{y^{2} }{b^{2} } - \frac{x^{2} }{a^{2} } = 1$ -

We presume that the y-axis is where the hyperbola's longer axis lies.

In this instance, the sound traveled a total of 1100 meters, and the value of a can be calculated as follows:

2a = 1100

a = 550ft

Given that the two people are 3 miles apart, we can calculate the value of c in feet as follows:

1 mile = 5280 feet

∴ 3 miles = 15840 ft = c

And this is how we may determine what b is worth:

$b^{2} = c^{2} - a^{2}$

$b^{2} = 15840^{2} - 550^{2}$

$b^{2} = 250603100$

Our equation is thus given by:

$\frac{y^{2} }{250603100 } - \frac{x^{2} }{550^{2} } = 1$

And for this case we want to find the value of x when y = 3ft=15840ft and solving for x we get,

$\frac{15840^{2} }{250603100 } - \frac{x^{2} }{550^{2} } = 1$

$\frac{15840^{2} }{250603100 } - 1 = \frac{x^{2} }{550^{2} }$

$1.001- 1 = \frac{x^{2} }{550^{2} }$

$0.001 = \frac{x^{2} }{550^{2} }$

$302865.145= {x^{2}$

x = 550.331 ft.

The fireworks display occur at 550.331 ft.

What is a solution for 11/12

elena-s [515]

Answer:

It is either 11/12 or 0.91666666667.....

Step-by-step explanation:

Because this can not be actually divided into a "number" like 2 or 5, we can only get a approximate. Like the top answer.

Round to the nearest ten is 0.9

Round it to nearest hundredths is 0.92
