Answer:169pi

Step-by-step explanation:

Circumference(c)=26pi

Circumference(c)=2 x pi x radius(r)

26pi=2pi x r

Divide both sides by 2pi

26pi/2pi=(2pi x r)/2pi

13=r

Radius(r)=13

Area of circle=pi x r^2

area of circle=pi x 13^2

Area of circle=169pi

Simplify each expression.<br> (-3)¹/₃ . (-3)¹/₃ . (-3)¹/₃
babymother [125]

The result of simplifying each number (-3)¹/₃ . (-3)¹/₃ . (-3)¹/₃  using the exponent rules is -3

To solve this exercise we have to resolve algebraic operations following the exponent rules.

(-3)¹/₃ . (-3)¹/₃ . (-3)¹/₃

Using the product rule that indicates that: the exponent result will be the addition of these exponents, we have:

(-3)¹/₃⁺ ¹/₃ ⁺ ¹/₃

(-3)³/₃

(-3)¹

-3

<h3>What is an exponent?</h3>

In mathematics an exponent is the number of time that a number, called (base) is multiplied by itself. It is also called, power or index.

Example: 3² = 3*3 = 9

What is the volume of a cylinder with a diameter of 8 name m and a height of 5.5
Cerrena [4.2K]

To begin, you must plug all the values you have into a formula, and also putting them in the right form.

The formula for the volume of a cylinder is: πr²h

FINDING RADIUS: With this in mind, now we know that, our diameter must be converted to a radius. To do this, you divide your diameter by two. This gives you, 4 as your radius.

FINDING HEIGHT: In the question you sent, you can tell they've given you, your height, so all you need to do is plug it into the equation.

PLUGGING IT IN:

Your pi, stays the same when using a calculator, just press your pi symbol depending on the calculator you are using. Your radius is 4, therefore it wants you to square it, which is 4x4, which equals 16. Next, you want to multiply it by the height, so just multiply it with your height, 5.5

276.46m
