Answer:

Area of sector = 2.355 miles²

Step-by-step explanation:

Formula:

Area of circle = πr²

Where r is the radius

Area of sector = πr²(C/360)

Where C is the angle of sector

It is given that radius of circle is 6 miles

<u>To find the are of circle</u>

Here diameter = 6 miles,

radius r = diameter/2 = 3 miles

Area = πr² = 3.14 * 3² = 28.26 miles²

<u>To find area of sector</u>

Here r = 3 and C = 30°

Area of sector = πr²(C/360) = 28.26*(30/360)

= 2.355 miles²

Answer: 2.35 square miles.

Step-by-step explanation:

To solve this exercise you must apply the formula for calculte the area of a sector in a circle, which is shown below:

A=r^2\pi(\frac{C}{360})

Where C is the central angle in degrees and r is the radius.

Therefore, knowing that:

C=30\°\\r=\frac{6mi}{2}=3mi

When you substitute values, you obtain the following result:

A=(3mi)^2\pi(\frac{30\°}{360})

A=2.35mi^2

SSSSS [86.1K]

                                                 <u>4h + 7 = 4h - 3</u>

Subtract  4h  from each side:            7 = -3

There is no value of  ' h ' that can make this a true statement,
so the equation has no solution.

HELP!
bearhunter [10]
Here is how you would work it out step by step.

You have to factor the equation you're given. (To check you factorization you can "FOIL" it and make sure it matches the original equation)

Then set the two answers you get from FOILing to zero and you should get your answers.
