The radius of a circle is 7m , find its area in terms of π

dangina [55]

Answer:

49π

Step-by-step explanation:

A = π $r^{2}$

A = π $7^{2}$

A = 49π

For the one you put in the comment...

The radius of a circle is 19cm find its area in terms of π

A = π $r^{2}$

A = π 1 $9^{2}$

A = 361π

For the other one you put in the comment

The radius of a circle is 4 cm find its area in terms of π

A = π $r^{2}$

A = π $4^{2}$

A = 16π

For the other one you put in the comment

The radius of a circle is 20 cm find its area in terms of π

A = π $r^{2}$

A = π $20^{2}$

A = 400π

Hope this helped!

Have a supercalifragilisticexpialidocious day!

How many repeating digits are in the smallest group of repeating digits in the decimal equivalent of 2/9

AVprozaik [17]

Answer:

The answer is A.

Step-by-step explanation:

First, divide two by nine. The result is the decimal zero point two repeating.

Second, the digit that repeats is two. So, since two is one digit, the answer is A.

If f(x)=2x^3-6x^2-16x-20f(x)=2x *3 −6x *2−16x−20 and f(5)=0, then find all of the zeros of f(x)f(x) algebraically.

mihalych1998 [28]

The zeros of the cubic function f(x) = 2x³ - 6x² - 16x - 20 are given as follows:

x = 5, x = -1 + i, x = -1 - i.

<h3>How to obtain the solutions to the equation?</h3>

The equation is defined by the rule presented as follows:

f(x) = 2x³ - 6x² - 16x - 20.

One solution for the equation is given as follows:

x = 5.

Because f(5) = 0.

Then (x - 5) is a linear factor of the function f(x), which can be written as follows:

2x³ - 6x² - 16x - 20 = (ax² + bx + c)(x - 5).

This is because the product of a linear function and a quadratic function results in a cubic function.

Now we expand the right side to begin finding the coefficients of the quadratic function that we are going to solve to find the remaining zeros:

2x³ - 6x² - 16x - 20 = = ax³ + (b - 5a)x² + (c - 5b)x - 5c.

Then these coefficients are obtained comparing the left and the right side of the equality as follows:

a = 2.

-5c = -20 -> c = 4.

b = -6 + 5a = 4.

Hence the equation is:

2x² + 4x + 4.

Using a quadratic equation calculator, the remaining zeros are given as follows:

x = -1 + i.

x = -1 - i.
