I do suppose that you refer to adding these quantities:
6/1 + 21 = 6 + 21 = 27
<span>and
6/10 + 21
</span>= 3/5 + 21
= 3/5 + 105/5
<span>= 108/5</span>

What is the circumference if the diameter is 21in and pi is 22/7

Ede4ka [16]

Answer:

66 in

Explanation:

the circumference can be calculated as:

$C=d\cdot\pi$

Where d is the diameter and π is 22/7.

So, replacing the values, we get:

$C=21\cdot\frac{22}{7}=\frac{21\cdot22}{7}=\frac{462}{7}=66\text{ in}$

Therefore, the circumference is 66 in.

Simplify each expression as much as possible, and rationalize denominators when applicable. . √36/√18= ?

tino4ka555 [31]

Answer:

√2

Step-by-step explanation:

Solving the given expression step by step:

$\frac{\sqrt{36} }{\sqrt{18} } = \frac{6}{3\sqrt{2} }\ \ \ [\because \sqrt{36} = 6 \ and \ \sqrt{18} = 3\sqrt{2}] \\ = \frac{3 \times 2}{3\sqrt{2} } = \frac{ 2}{\sqrt{2} }= \sqrt{2}$

We rationalize denominator and change it into a simpler form as soon as possible.
