The radius of the circle is 2.86 cm.

Step-by-step explanation:

Given,

The circumference of the circle = 18 cm

To find the radius of the circle.

Formula

The circumference of a circle of radius r is 2πr

According to the problem,

2πr = 18

or, r = \frac{18X7}{22X2} = 2.86 (approx)

Hence,

The radius of the circle is 2.86 cm.

Go step by step to reduce the radical of the equation given. (Figure the step for the box)
Rama09 [41]

\sqrt{32} ~~ \begin{cases} 32=2\cdot 2\cdot 2\cdot 2\cdot 2\\ \qquad 2^4\cdot 2\\ \qquad 2^{(2)(2)}\cdot 2\\ \qquad (2^2)^2\cdot 2 \end{cases}\implies \sqrt{(2^2)^2\cdot 2}\implies 2^2\sqrt{2}\implies 4\sqrt{2}

So, the anti derivative= x^2 -.8x +C. Ignore C.
Plug in 2= 4-(2)(.8)=2.4
Plug in .4= .16-(.4)(.8)=-.16

9880 different possibilities are there in Sally's new combination option second 9880 is correct.

<h3>What is permutation and combination?</h3>

A permutation is the number of different ways a set can be organized; order matters in permutations, but not in combinations.

We have:

Total unique numbers consists in a Sally locker = 3

From the digits 0 to 39

Total numbers = 40

Apply combination formula:

= C(40, 3)

= 40!/(3!37!)

= 9880

Thus, 9880 different possibilities are there in Sally's new combination option second 9880 is correct.
